Fort of São João das Maias 🏰 Oeiras

The Fort of São João das Maias, also known as the Fort of Oeiras, is located on the right bank of the River Tagus estuary, in the municipality of Oeiras in the Lisbon District of Portugal. It was constructed between 1644 and 1653 by António Luís de Meneses, 1st Marquis of Marialva to reinforce the defence of the capital in the context of the Restoration War between 1640 and 1668, that culminated in the Treaty of Lisbon (1668) with Spanish recognition of Portuguese sovereignty. It was built to support the Fort of São Julião da Barra to its southwest, crossing fire with the Fort of São Lourenço do Bugio, situated in the middle of the estuary, and the Fort of Santo Amaro do Areeiro, situated between it and São Julião da Barra. It thus formed part of a line of fortifications that stretched from Cabo da Roca on the Atlantic coast to the Belém Tower, close to Lisbon. en.wikipedia.org/wiki/Fort_of_São_João_das_Maias
