Fort of Santo António da Barra, 16th century coastal fortress in São João do Estoril, Portugal.
The fort displays a star-shaped irregular polygon layout with two outer bulwarks, vaulted barracks, and a central building containing a chapel dedicated to Saint Anthony.
Military engineer Giovanni Casale constructed the fortress in 1590 under Philip II of Spain to protect against English and Dutch naval threats along the Tagus estuary.
The fortress received Monument of Public Interest status in 1977, marking its importance in Portuguese maritime defense architecture and military engineering.
Visitors can explore the fortress during weekends and public holidays from 10:00 to 18:00, with guided tours provided by the Cultural and Educational Service.
The fort served as the summer residence of Prime Minister António de Oliveira Salazar until 1968, when he suffered a stroke within its walls.
