This is the third in a series of four volumes that are intended to present a complete Corpus of all the church buildings that were built, rebuilt or simply in use in the Crusader Kingdom of Jerusalem between the capture of Jerusalem by the First Crusade in 1099 and the loss of Acre in 1291. This volume deals exclusively with Jerusalem, the capital of the Kingdom from 1099 to 1187. It contains descriptions and discussion of some 90 churches and chapels, accompanied by plans, elevation drawings and photographs.
