A Philippine-era fort located on the Tagus River, construction began in the 16th century. The first lighthouse was built there in the 18th century. This original circular fortress is an example of Renaissance fortresses.

Built by King João IV in 1647, this fort was part of the defensive system of the Tagus River mouth. Over the centuries, it has been used and adapted in various ways, including as a customs post, a youth sailing center, and a youth hostel.

This fort, built at a strategic point that allowed it to dominate the entrance to the bar, was one of the most important Portuguese military bases. It is one of the best-preserved forts and the most perfect example of its 16th-century type, originating from Italy. Its esplanades, vaulted casemates, and cistern are notable.

It also features reconstructions of parts of typical Alentejo homes, such as the kitchen, pantry, bedroom, and sewing room.
