Cambridge: a chapel of kings, a bridge Newton never built

Cambridge is a medieval market town on a river crossing, a crowd of colleges, a nest of scientists and a keeper of odd customs, and many of its landmarks hide a surprise. This quiz invites you to test what you know about the city in 20 questions with pictures.

Who planned the great chapel on King's Parade, and what is the stone ceiling above its long nave? Did the river give the place its name, or was it the reverse? Where did the first masters come from in 1209, what did the oldest college get for its six-hundredth birthday, and who, unusually, founded the college with the creeper-covered court?

What really holds the timber bridge at Queens' together, which famous fair in literature grew from a market beside the Cam, and what does the marble scientist in Trinity's ante-chapel carry? What do students attempt in Great Court at noon, what did the old carrier's customers really get to pick, and how did a church's chime reach the banks of the Thames?

What was lowered from the Senate House gallery, why did a bishop pay for a young astronomer's first building, what lies hidden at Sidney Sussex, which animal did a poet bring to college, which shrine is copied in the church on Bridge Street, who sent a beetle-collector on a long voyage, where was the double helix announced over lunch and when did women at last become members?

The pictures are colour photochroms, old photographs, engravings, a lithograph, a map, paintings, a watercolour and a miniature, all in the public domain.
