Forte de Santa Maria da Arrábida

Forte de Santa Maria da Arrábida is a stone fortress near Azeitão positioned at the base of the Arrábida mountain range. It features a hexagonal earthwork design with four bastions oriented toward the sea.

It was constructed between 1749 and 1751 during King John V's reign as a strategic defense post for the Setúbal river mouth. The fortress guarded the harbor entrance and nearby coastline from maritime threats of that era.

The oceanographic collection inside houses exhibits about sea creatures and coastal ecosystems of the region. It reveals how the fortress role extended beyond defense to become a center for understanding local marine life.

The fortress is accessible on several days throughout the week, best visited in the morning for clearer sea views. Wear comfortable shoes since the paths leading to and around the structure are uneven in places.

Inside there is a small chapel holding a carved image of the Virgin Mary from the 17th century, made from local limestone. This religious artifact links the fortress military purpose with the spiritual beliefs of its community.
