After seeing the reconstructed court of Baldwin I at the Montreal Castle, watch for these double arches of sandstone. These small chambers once served as baths and were later used by the Mamluks as a school. From there you are only a few steps away from another watchtower. This semicircular keep was constructed by the Mamluks in the late 13th century. An interesting historical note is the Mamluks used carrier pigeons to rapidly communicate between their castles.
