The São Julião Fort is certainly the largest maritime defense construction in Portugal. In the 16th century, during the reign of D. João III, the construction of the Fort began. Miguel Arruda is responsible for the construction of this work, being one of the most famous architects of the time.

In addition, the Fort was expanded over the centuries, as its strategic position was considered of great importance for the defense of the entrance to the Tagus. In this way, the city of Lisbon could be protected from enemy attacks from the sea.
