Exchequer Gate, Lincoln. There were many gates to the original Cathedral Close of which three (plus a posterngate) still exist today. This shot is of Exchequer Gate which dates from the 14th century and was taken from within the Close. This gate is believed to have been the main entrance into the Close, certainly it is the most impressive of those still standing having a large archway in the middle and a postern on either side with two storeys of rooms above which at one time were let as dwellings.
