The Little Fort of Ponta da Bandera, also known as the Fort of Our Lady of Pena de Franca or Fort Lagos, is located on the waterfront in the town of Lagos, which has been the administrative capital of the Algarve since 1577. Built around 1690, this fort was part of the important defensive structures guarding the port. From the raids of pirates and Spaniards, the army used it until the twentieth century, and it was restored in the sixties of the twentieth century, and today the interior of it is open to the public for a small entrance fee.
