caption_attribution_description: English: Remains of the Fort of Ajuda Pequeno, one of the forts in the Lines of Torres Vedras near Bucelas, just north of Lisbon, Portugal
context_page_description: The Forts of Ajuda are located in the parish of Bucelas, in the municipality of Loures in the Lisbon District of Portugal. Just a short distance apart, the Forts of Ajuda Grande and Ajuda Pequeno were built in 1810 as part of the Lines of Torres Vedras, which were defensive lines to protect the Portuguese capital Lisbon from invasion by the French during the Peninsular War.
context_section_description: Built at an altitude of 311 metres, Ajuda Grande (also known as the Fort of Alrota) was planned to control the road that connected Sobral de Monte Agraço, where the French were repulsed, with Bucelas. It was built as an irregular polygon with eleven sides, with two connected bulwarks and with three access points, and is surrounded by a dry moat.  Inside, there is a magazine, five embrasures and two traverses. The fort was designed for a garrison of 300 men and is believed to have had four 12-pounder cannon. All of the works on the Lines were numbered and Ajuda Grande was No. 18, forming part of District 5 of the second line. As part of the celebrations of the bicentennial of the Lines of Torres Vedras in 2010, the fort was recently restored. The site also contains a survey marker.
