In 1588, with the approval of Cardinal Alberto, the Vice-Regal representative,
Filippo Terzi initiated construction of the
Fort of Nossa Senhora da Queimada, part of a project that also included the building of an artificial port to link the island of Pessegueiro to the mainland. Alexandre Massay took Terzi's place in 1590, when construction of the
Fort of Santo Alberto (a project which had been proposed two years previously), began on Pessegueiro. In 1755, the famous
Lisbon earthquake resulted in damage to the chapel and the batteries situated over the casemates. Between 1877 and 1942, the fort was occupied by a contingent of the
Fiscal Guard (
Guarda Fiscal). Following its abandonment, a project was conceived in 1962 to convert the fort into a hostel, but was never approved or initiated. On 18 July 1957, a decree classified the Fort of Pessegueiro, including the island of the same name, as a national heritage; this classification was clarified by a new decree on 21 December 1974. Between 1983 and 1985, repairs were made to the exterior parapets of the left bastion and central zone (the former port entrance) by the
Direcção Geral dos Edifícios e Monumentos Nacionais (DGEMN). Ruined sections were reconstructed and areas in risk of damage along the exterior walls were reinforced. ==Architecture==
