Fort of Alqueidão

The Fort of Alqueidão sits on Monte Agraço and is a restored military fortification with preserved barracks, warehouses, and viewing platforms. The complex demonstrates the communication and observation systems that connected an entire defensive network.

The fort was built between 1809 and 1810 under Colonel Richard Fletcher's supervision as part of the Lines of Torres Vedras against Napoleon. This defense line was a British-Portuguese strategy to repel an invasion.

The fort displays Portuguese military design from the early 19th century with advanced defensive methods. The restored structures show how soldiers lived and worked during that period.

Access is straightforward and pathways are well marked to explore the main buildings. Visitors should wear sturdy shoes as the terrain is uneven and there is little shade throughout the site.

The fort was once one of the largest installations in this defensive series, housing hundreds of soldiers with numerous cannons stationed throughout. Today many of these military details remain visible in the restored structures.
