Portugal. Lisbon. View on the city center, Saint George's Castle, Tagus river and the 25 de Abril Bridge. Saint George's Castle (São Jorge Castle) is a historic castle located in the freguesia of Santa Maria Maior. Human occupation of the castle hill dates to at least the 8th century BC while the oldest fortifications on the site date from the 2nd century BC. The hill on which Saint George's Castle stands has played an important part in the history of Lisbon, having served as the location of fortifications occupied successively by Phoenicians, Carthaginians, Romans, and Moors, before its conquest by the Portuguese in the 1147 Siege of Lisbon. Since the 12th century, the castle has variously served as a royal palace, a military barracks, home of the Torre do Tombo National Archive, and now as a national monument and museum. The 25 de Abril Bridge is a suspension bridge connecting the city of Lisbon to the municipality of Almada on the left (south) bank of the Tagus River. It has a main span length of 1,013 metres. Lisbon is the capital and largest city of Portugal. 21.05.2024 © 2024 Didier Ruef
