The Cabo da Roca Lighthouse (Portuguese: Farol de Cabo da Roca) is a beacon/lighthouse located 165 metres (541 ft) above the Atlantic Ocean, on Portugal's (and continental Europe's) most westerly extent (Cabo da Roca). It is located in the civil parish of Colares, in the municipality of Sintra, situated on a promontory that juts out into the ocean, made up of granite boulders and interspersed limestone. It is a third-order lighthouse, which originally began operating in 1772.
