The Backs
The Backs is one of the most celebrated and photographed landscapes in all of England, a sweeping green corridor that runs along the western banks of the River Cam as it winds through the heart of Cambridge. The name refers to the college backs — the rear grounds of several of Cambridge University's oldest and most prestigious colleges, which face the river rather than the city streets. It is a place where manicured lawns, ancient stone bridges, weeping willows, and the reflections of collegiate architecture combine to create a scene of almost implausible beauty. Visitors come from across the world to walk along this stretch, to hire punts and drift lazily beneath the bridges, and to experience something that feels entirely removed from the modern city just a short walk away. It is simultaneously a public amenity, a working college environment, and a piece of living history that has changed relatively little in centuries.
The origins of The Backs as a unified landscape concept developed gradually over many centuries, shaped by the expansion of the colleges that line it. King's College, Clare College, Trinity College, St John's College, and Queens' College are among the institutions whose grounds constitute The Backs. King's College was founded by Henry VI in 1441, and its chapel, completed in the early sixteenth century, looms magnificently over the landscape. Trinity College, established by Henry VIII in 1546 from the merger of earlier foundations, contributes some of the grandest grounds of all. The relationship between the colleges and the river was not always as picturesque as it appears today — the river was for centuries a working waterway used for transport and the delivery of goods, and the grounds behind the colleges were often more utilitarian than ornamental. The deliberate landscaping into the park-like setting familiar today took place largely during the eighteenth and nineteenth centuries, influenced by the fashionable landscape movement of the era.
The bridges of The Backs are among its most famous features and each has its own character and story. The Mathematical Bridge, officially the Queens' College Bridge, was constructed in 1749 and is frequently — and incorrectly — said to have been designed by Isaac Newton and originally built without bolts, held together by geometric forces alone. In fact, Newton died in 1727 and never saw it, and the bridge has always used bolts; the story persists because it is irresistible, and guides on punts repeat it with cheerful frequency. Clare Bridge, built in 1640, is the oldest surviving bridge in Cambridge and is notable for the fourteen stone balls along its balustrades — one of which has a segment missing, a detail attributed in legend to a dispute over payment with the stonemason. The Bridge of Sighs at St John's College, a covered stone bridge built in 1831, takes its nickname from the enclosed bridge in Venice, though scholars note it bears a stronger resemblance to the Rialto Bridge.
In person, The Backs offers a sensory experience of exceptional richness. On a clear spring morning, the air carries the smell of freshly cut grass and the faint mineral cool of the river, and birdsong from the willows and chestnut trees fills the open spaces between the colleges. The river itself moves slowly and greenly here, and the sound of punt poles dropping into the water and the low murmur of guides narrating the history provide the gentle soundtrack of the summer season. In autumn, the lawns turn gold and rust beneath the trees, and the crowds thin considerably, leaving the paths quieter and the atmosphere more contemplative. In winter, with frost on the grass and mist above the river, The Backs achieves a kind of austere grandeur that the summer postcard versions rarely capture. Certain stretches of lawn belong to the colleges and are not publicly accessible — members of the public are respectfully asked to keep to the footpaths and the riverbanks, and signs make clear where private college ground begins.
The surrounding area places The Backs within the broader fabric of central Cambridge, one of England's most architecturally dense and historically layered cities. King's Parade, with its bookshops, cafes, and the exterior view of King's College Chapel, is only minutes away on foot from the eastern edge of The Backs. The Market Square, the Round Church — one of the oldest in England — and the grand Senate House are all within easy walking distance. Punting hire stations operate from several points along the river, including Silver Street Bridge and Magdalene Bridge, and both chauffeured and self-hire punts are available. The University Botanic Garden, a world-class collection of plant species spread across sixteen hectares, lies about a mile south and makes an excellent complement to a visit.
For those arriving by public transport, Cambridge railway station is around a twenty-minute walk from The Backs, and regular bus services connect the station to the city centre. Cycling is the mode of transport most naturally suited to Cambridge, and the city has extensive cycling infrastructure. The Backs is accessible on foot year-round and is free to walk through, though visitors should be mindful that some grounds are private college property. The best times to visit are early morning in spring and summer, before the punt traffic builds and the tourist numbers swell, or in the quieter months of late autumn and early winter. Guided walking tours depart from the city centre regularly and often include the exterior of The Backs, while the river view from a punt remains one of the most memorable perspectives available anywhere in the country.
A handful of additional details add texture to any visit. Isaac Newton, who studied and later taught at Trinity College, is said to have conducted early optical experiments in the rooms overlooking these grounds. Lord Byron, during his time at Trinity in the early nineteenth century, reportedly kept a pet bear in his rooms — college rules forbade dogs but made no mention of bears — and would sometimes walk the animal along the riverbank. The lawns of King's College are famously and firmly off-limits to all but Fellows and certain invited guests, a tradition maintained with quiet but absolute firmness for centuries. The annual May Bumps rowing races take place on the Cam south of The Backs each June (confusingly, as Cambridge terminology dictates that "May Week" occurs in June), and the atmosphere during race week transforms the riverside entirely. The Backs is not merely a backdrop to Cambridge life — it is, in many respects, the soul of it.
