Jesus Green Lock (far left), taken from the visitor moorings below, and showing the weir (far right) with the sluice in between. Powered boats are only allowed above the lock between October and March. The boaters' services are on the left just out of picture. There is room for about 5 narrowboats along the length of the mooring (10 breasted).
Photos two and three show two of the University Colleges - two is Corpus Christi, three is Jesus College.
Photo four is of the Pitt Building. Completed in 1833, it had been commissioned in honour of William Pitt the Younger (an undergraduate of Pembroke College) and planned to house the Cambridge University Press. After a major refurbishment, it is now a conference centre.
Photo five is of the market, with Great St Mary's Church in the background.
