 Clare has a much-photographed bridge over the River Cam and is the oldest of Cambridge's current bridges.It was built of stone in 1640 by Thomas Grumbold and restored in 1969, and is a Grade I listed building.<ref></ref>

Fourteen stone balls decorate it, one of which has a missing section.A number of apocryphal stories circulate concerning this – the one most commonly cited by members of college is that the original builder of the bridge was not paid the full amount for his work and so removed the segment to balance the difference in payment.
