Cambridge grew up around a Roman-era crossing of the River Cam, on the route between London and the north. A market town took root by the crossing, and from the 13th century onward scholars fleeing town-and-gown riots in Oxford, and later independent founders — bishops, kings, queens and guilds — endowed a string of self-governing colleges along the river's banks. This 3D map plots the Cam and 22 of its best-known colleges in the order they were founded.
King's College Chapel, begun by Henry VI in 1446, has one of the largest fan-vault ceilings in the world, and its stained glass is almost entirely original Tudor glasswork that survived the Reformation and the Civil War intact.
A 3D map of the River Cam winding through Cambridge, with 22 colleges rising along its banks in the order they were founded — scrub the timeline from the Roman river-crossing to the newest 20th-century colleges.
Cambridge's college system grew in visible waves — a medieval cluster near the old town centre, a Tudor boom along the river's "Backs," and later expansions for science and for women's education. Watching the timeline fill in shows those waves directly.
