The Fort of Monsanto, also known as the Marquês de Sá da Bandeira Fort, is located at the top of the Monsanto hill in the Monsanto Forest Park, in Lisbon, Portugal. Built at the end of the 19th century as part of Lisbon's Campo Entrincheirado (Entrenched Field) defensive ring around the city, the fort is now a maximum-security prison.
