 To the west of the Grand Shaft Barracks (across the Centre Road, close to the North Gate) a number of buildings were added in the 1860s to serve the whole Western Heights garrison, including a Garrison Chapel and School.A Military Hospital had already been built to the south in 1804-06; extended in the 1860s, it latterly served as a headquarters for the Royal Engineers.These garrison buildings, along with both the Grand Shaft Barracks and South Front Barracks, were almost entirely demolished in the 1960s.
