The Corigliano d’Otranto Castle was constructed during the 16th Century when Giovan Battista delli Monti drastically changed a building that already existed in the 1400s turning into a fortress. In the late part of Delli Monti’s domination, the castle changed hands and was home to the Trani family. The new owners made a ducal mansion out of the castle in 1667 with the structural and decorative input of the architect Francesco Manuli. Previous changes were made on the fosse, parade ground, and the four corner towers each of which bears a relief of the saint it is dedicated to.
