Cambridge is famous for its university, magnificent colleges and beautiful River Cam. But behind the postcard-perfect architecture lies a much older and more surprising history.

Did you know that one of Cambridge's most unusual churches was built before the university existed? Or that the city's famous Mathematical Bridge has nothing to do with Isaac Newton, despite what many visitors have heard?

These are the kinds of stories that make exploring Cambridge so rewarding.

At We Are Cambridge, our student guides love introducing visitors to the details that are easily missed when walking through the historic city centre. Sometimes, a small architectural feature or an unusual street name can reveal more about Cambridge's past than an entire guidebook.

One of our favourite places to begin is the Round Church on Bridge Street. With its distinctive circular structure and nearly 900 years of history, it provides the perfect introduction to a different side of Cambridge.

Here are seven fascinating facts that might change the way you see this extraordinary university city.

1. Cambridge Was Already a Town Before Its Famous University Existed

Most visitors associate Cambridge with the university, which traces its origins to 1209. However, Cambridge had already been an established settlement for centuries.

The Romans maintained a settlement in the area around Castle Hill, and the town later developed through Anglo-Saxon and medieval periods.

Its location near the River Cam made it an important place for trade and communication. Markets, churches and residential communities existed long before university scholars arrived.

One of the best reminders of this earlier history is the Round Church, officially known as the Church of the Holy Sepulchre.

Built around 1130, it is approximately 80 years older than the university.

This makes the Round Church particularly fascinating because it represents a period of Cambridge history that is often overshadowed by the colleges.

Today, the church stands at the junction of Bridge Street and Round Church Street, surrounded by cafés, shops, cyclists and pedestrians.

It is easy to walk past without realising that the building was already standing when Cambridge's academic history began.

Visitor tip: If you are exploring the city independently, begin your walk around Bridge Street before heading towards Trinity Street and King's Parade. This allows you to discover Cambridge's medieval origins before reaching its famous university colleges.

Our Shared 90-Minute Cambridge Walking Tour introduces visitors to the relationship between the historic town and the university, helping explain how the two developed alongside one another.

2. The Round Church Has an Unexpected Connection to Jerusalem

At first glance, Cambridge's Round Church looks very different from the traditional English churches found throughout the country.

Instead of a long rectangular nave and tall Gothic tower, it has a circular central structure, thick stone columns and distinctive Norman arches.

Why?

The answer lies thousands of miles away in Jerusalem.

The Round Church was inspired by the Church of the Holy Sepulchre, one of Christianity's most important religious sites.

During the medieval period, the Jerusalem church was associated with the traditional locations of Jesus Christ's crucifixion, burial and resurrection.

Its architecture influenced religious buildings throughout Europe, including a small number of round churches in England.

Cambridge's Round Church is one of only four surviving medieval round churches in the country.

Its circular design reflects the influence of the rotunda associated with the Holy Sepulchre in Jerusalem.

There is also a common misconception worth correcting.

Because some round churches were associated with the Knights Templar, visitors sometimes assume that Cambridge's Round Church was built by them.

However, the Cambridge church is traditionally associated with the Fraternity of the Holy Sepulchre, and its history should not be confused with that of the Templars.

This is a wonderful example of how a building's true history can be more interesting than the legends surrounding it.

Visitor tip: Take a moment to examine the rounded entrance arches and thick stone columns. These are characteristic features of Norman architecture and look very different from the pointed Gothic arches of later Cambridge buildings.

3. The University of Cambridge Does Not Have One Main Campus

Visitors are often surprised to discover that the University of Cambridge does not resemble a conventional modern university campus.

There is no single entrance gate leading into one enormous university complex.

Instead, Cambridge is a collegiate university made up of 31 colleges alongside academic departments, libraries and other university institutions spread throughout the city.

Each college has its own history, buildings, traditions and community.

Some colleges were founded in the medieval period, while others were established much more recently.

Peterhouse, founded in 1284, is the university's oldest college. Trinity College was founded by Henry VIII in 1546, while Churchill College was founded in 1960.

This variety explains why Cambridge's architecture is so diverse.

As you walk through the city, you encounter medieval gateways, Tudor courtyards, Gothic chapels, classical façades and modern academic buildings.

The university has grown gradually over more than eight centuries rather than being designed as one unified campus.

For first-time visitors, understanding this collegiate structure makes exploring Cambridge much more enjoyable.

Rather than searching for a single university entrance, you can discover the individual stories behind different colleges.

Our Private 90-Minute Cambridge Walking Tour is particularly suitable for families, prospective students and visitors who want to ask detailed questions about Cambridge's colleges and university traditions.

Visitor tip: Remember that individual colleges have their own visitor policies. Some may close to the public during examinations, ceremonies or other university activities, so check current access arrangements before travelling.

4. Cambridge's Mathematical Bridge Was Not Designed by Isaac Newton

One of the most popular stories told about Cambridge concerns the Mathematical Bridge at Queens' College.

According to the legend, Isaac Newton designed the bridge without using any nuts or bolts. Later, students supposedly dismantled it to understand how it worked, only to discover that they could not reconstruct it without additional fixings.

It is a memorable story, but it is not historically accurate.

The Mathematical Bridge was first built in 1749, while Isaac Newton died in 1727.

Newton therefore could not have designed the bridge.

The original bridge was designed by William Etheridge and constructed by James Essex.

Its distinctive appearance comes from the clever arrangement of straight wooden members into a structure that follows a curved form.

Although it looks like an arch, the bridge's geometry demonstrates how carefully arranged straight timbers can create an elegant and structurally effective design.

The bridge has been rebuilt over time, but its famous appearance has been retained.

This is one of the reasons a knowledgeable guide can make such a difference when exploring Cambridge.

The city is full of popular stories, and distinguishing historical evidence from entertaining legend helps visitors appreciate its heritage more deeply.

Visitor tip: The Mathematical Bridge is particularly enjoyable to view from the River Cam, where its geometric structure can be appreciated from below and from the water.

Our Shared Cambridge Punting Tour offers approximately 45–50 minutes of traditional river sightseeing, with the classic College Backs route passing some of Cambridge's most celebrated bridges and college buildings.

5. Cambridge's Famous Bridge of Sighs Is Not as Old as It Looks

The Bridge of Sighs at St John's College is one of Cambridge's most photographed landmarks.

With its enclosed passageway, decorative windows and Gothic Revival architecture, it looks as though it could belong to the medieval period.

However, the bridge was completed in 1831.

That makes it much younger than many of the surrounding college buildings.

Its design reflects the 19th-century Gothic Revival movement, which drew inspiration from medieval architectural traditions.

The name recalls the famous Bridge of Sighs in Venice, although the two bridges are architecturally quite different.

Cambridge's version connects parts of St John's College across the River Cam.

One of the most enjoyable ways to see it is from a traditional wooden punt.

From the water, visitors can admire the bridge's enclosed structure, elegant arches and the historic college buildings surrounding it.

This perspective is difficult to appreciate fully from the nearby streets.

For couples, families or groups who prefer a more exclusive experience, our Private Cambridge Punting Tour provides a boat reserved for their own party.

It is a wonderful way to enjoy Cambridge's riverside scenery, particularly during the warmer months.

Visitor tip: If photography is important to you, consider how the weather and time of day may affect the light. Overcast conditions can be useful for capturing architectural details without strong shadows, while sunny days create beautiful reflections on the water.

6. Some of Cambridge's Most Important Historical Stories Are Hidden in Its Streets

Cambridge's most famous landmarks are impressive, but the city's smaller details can be equally revealing.

Consider the contrast between the Round Church and King's College Chapel.

The Round Church was built around 1130 and reflects Norman architectural traditions, including rounded arches, thick stone walls and a sense of solidity.

Construction of King's College Chapel began in 1446, more than three centuries later.

Its soaring windows, intricate stonework and magnificent fan vaulting demonstrate the extraordinary development of English Gothic architecture.

By walking between these two buildings, visitors can experience several centuries of architectural history within a relatively small area.

The surrounding streets also reveal how the university and town developed together.

Historic market spaces, churches, college gateways and residential buildings coexist throughout central Cambridge.

This creates a distinctive atmosphere in which medieval history remains part of everyday life.

Our Shared 2.5-Hour In-Depth Cambridge Tour is designed for visitors who want to go beyond a quick introduction and explore the university's history in greater detail.

For educational groups, architecture enthusiasts and travellers with particular interests, our Private 2.5-Hour In-Depth Cambridge Tour provides greater flexibility to focus on specific themes.

Visitor tip: When exploring Cambridge, occasionally look above street level. Decorative stonework, old inscriptions, unusual windows and historic architectural features are often easier to notice when you slow down.

7. Cambridge Is More Than a University City — It Is Also a Centre of Art and Culture

The university's academic reputation sometimes overshadows Cambridge's remarkable cultural attractions.

One of the best examples is the Fitzwilliam Museum.

Founded in 1816, the museum houses an internationally important collection of art and antiquities.

Its galleries include paintings, sculpture, ceramics, manuscripts and objects from ancient civilisations.

Visitors can explore artistic traditions from different periods and regions, making it an excellent addition to a Cambridge itinerary.

The museum also provides an interesting contrast with the university's historic colleges.

While Cambridge's streets reveal the development of the city itself, the Fitzwilliam Museum connects visitors with a much broader history of art, culture and civilisation.

Our Shared Fitzwilliam Museum Tour introduces guests to selected highlights of the collections, while our Private Fitzwilliam Museum Tour offers a more personalised experience for those interested in particular artistic periods or historical subjects.

The city's cultural character is also visible in its everyday spaces.

Cambridge Market Square has been a centre of commercial activity for centuries, and today it remains a lively destination for food, independent traders and local life.

Nearby streets contain bookshops, cafés and historic buildings that make exploring the city enjoyable even without a fixed itinerary.

Visitor tip: If you have more than one day in Cambridge, consider dedicating your second day to museums, smaller historic churches and less familiar streets rather than trying to visit every attraction on your first afternoon.

How to Explore These Hidden Stories in One Cambridge Day Trip

One of the advantages of Cambridge is that many of its most interesting attractions are located within a walkable historic centre.

If you are travelling from London, direct trains operate from King's Cross and Liverpool Street, with journey times varying depending on the service.

For a first visit, we recommend beginning your day around Bridge Street and the Round Church.

This provides an introduction to Cambridge before the university and offers an opportunity to appreciate one of England's rare medieval round churches.

From there, continue towards Trinity Street and King's Parade to explore the university's historic colleges.

Along the way, take time to notice the architectural differences between the buildings.

A student-led walking tour can help connect these landmarks with the university's academic traditions, famous scholars and the wider history of the city.

After lunch around Market Square, enjoy a traditional chauffeured punting tour on the River Cam.

The College Backs offer a completely different perspective, with beautiful gardens, historic bridges and university buildings lining the river.

For first-time visitors, our 90-Minute Cambridge Walking Tour and Punting Combination brings together two of Cambridge's most memorable experiences in one convenient itinerary.

If you have additional time, visit the Fitzwilliam Museum or explore the smaller streets around the historic centre.

For visitors with specific interests, our Private Bespoke Cambridge Tour can be tailored around themes such as university history, medieval architecture, scientific discoveries or educational experiences.

The most important advice is not to rush.

Cambridge is a city that rewards curiosity. Sometimes, the best discoveries happen when you stop to examine an unfamiliar building or ask a question about something that catches your attention.

Discover the Cambridge That Most Visitors Miss

Cambridge's famous colleges and picturesque river scenery are certainly worth experiencing, but they represent only part of the city's extraordinary story.

Behind the familiar landmarks lies a much older history of medieval churches, market streets, architectural innovations and cultural connections that extend far beyond England.

The Round Church is a perfect example.

Its unusual circular shape may initially attract attention, but its real significance becomes clear when you discover its age, architectural origins and connection with medieval Jerusalem.

At We Are Cambridge, we believe these lesser-known stories make exploring the city especially rewarding.

Our student-led walking tours and traditional punting experiences are designed to help visitors understand not only what they are seeing, but why it matters.

Whether you are planning your first Cambridge day trip, visiting with family or returning to discover something new, there is always another fascinating detail waiting around the corner.

The best way to experience Cambridge is not simply to visit its famous landmarks, but to discover the unexpected stories that connect them.
