Jesus Lock

Jesus Lock is a lock on the River Cam in the north of central Cambridge, England. This is Lock No. 1 on the navigable portion of the River Cam. It was built in 1836 and is the only lock in the city. Jesus Green Lock Cottage, the former lock-keeper's cottage, is by the lock on Jesus Green. It is owned by the Conservators of the River Cam and is rented out to students.

The lock is located north of Jesus Green, which itself is north of Jesus College, hence the name. To the north of Jesus Lock is Chesterton Road (the A1303). To the east (downstream) is Victoria Avenue Bridge on Victoria Avenue and beyond that Midsummer Common, common land still used for grazing. Close by just downstream is Jesus Green Swimming Pool, a very long outdoor lido.

The stretch of river northeast (downstream) of Jesus Lock is sometimes called the lower river. The stretch between Jesus Lock and Baits Bite Lock is much used for rowing. There are also many residential boats on this stretch, their occupants forming a community who call themselves the Camboaters. The stretch above Jesus Lock is sometimes known as the middle river.
