 The Lady chapel, constructed to the east of the retro-choir, is a long narrow space, with large windows in the Decorated Gothic style of the late 13th century.The other buildings related to the cathedral are the free-standing bell-tower of the early 15th century, probably the work of William Wynford who also designed the cloisters, with openings in the Perpendicular style.St Mary's Almshouses in Chichester, which are linked to the cathedral, are a Christian charity dating from the 13th century.
