is the third version of the design, first built in 1749. King's College Bridge (1819) The first bridge on the site was built in the 15th century, and has been rebuilt several times before the current incarnation, designed by William Wilkins and built by Francis Braidwood. Clare College Bridge (1640) The oldest of Cambridge's current bridges, this bridge in classical style was built in 1639–40 by Thomas Grumbold (d.1659) It is one of two bridges left standing by the Parliamentarian forces in the Civil War (the other being the Great Bridge, a wooden bridge which has since been destroyed) when Cromwell used the stone from other bridges to refortify Cambridge Castle. Many different stories are told to explain the missing section of the globe second from the left on the south side of the bridge. One rumour is that the builder of the bridge received (what he considered to be) insufficient payment, and in his anger, removed a segment of the globe; another is that complete bridges were subject to a tax at the time it was built, and the missing segment made the bridge incomplete and hence untaxed. Garret Hostel Bridge (1960) At least the eighth bridge on this site on Garret Hostel Lane between the colleges of Trinity and Trinity Hall. The current design is by Timothy Guy Morgan, who at the time was an undergraduate student at Jesus College, after an open competition. Morgan died in 1960, before the bridge was completed. It was one of the first post-tensioned concrete bridges in the country. Known to students locally as “orgasm bridge”. Trinity College Bridge (1764) Designed by James Essex, it replaced a stone bridge built in 1651, which in turn replaced a stone bridge pulled down in 1643 by Cromwellian soldiers as a defence during the English Civil War. It is a Grade I listed building. Kitchen Bridge, St John's College (1709–11) Also known as St John's Old Bridge. The second oldest of Cambridge's remaining bridges, built by Robert Grumbold (1639–1720) according to designs by Sir Christopher Wren. The bridge was crafted from a single block of limestone, carved to give the appearance of masonry. Bridge of Sighs, St John's College (1831) Also known as New Court Bridge, it is probably Cambridge's best-known bridge, designed by Henry Hutchinson and based on a similarly named bridge in Venice, although the only real similarity between them is that they
