The Church of Ognissanti, also known as the Church of the Templars and whose apses reflect in the nearby port, was built by the Knights Templar during the first half of the XII century; its basilica plan includes three aisles divided by a colonnade, however there is no transept.

The entrance to the church is protected by a portico, a significant mark of Romanesque-Pugliese architecture.

The church hosts important paintings from the XVI century.
Norman knights were also vested here for the first Crusades, lead by Boemondo d'Altavilla.
