The Farol de Nossa Senhora da Guia is an active navigational lighthouse situated on a prominent cliff overlooking the North Atlantic in Cascais. Originally established in 1538 as a hermitage and watchtower, the current stone structure was built in 1761. The lighthouse has undergone multiple renovations, including a significant structural expansion in 1871 and electrification in 1952.
