Traditionally (but controversially) thought to be built by the Knights Templar in the 12th century, this church became a place of blessing for those setting out on Crusade. Legend has it that it was in this austere and dignified building that the knights of the First Crusade swore allegiance to their leader, Bohemond I of Antioch, before setting off to 'liberate' the Holy Lands. Whatever the truth, it's a treasured example of Pugliese-Romanesque architecture of the period.
