About this place
Guia Lighthouse (Farol da Guia) sits on Cabo da Guia in Cascais, about 2 km from the town centre, on the coast just west of the Tagus estuary. It is one of Portugal's oldest lighthouses, with roots going back to the early 1500s.
What are the key facts?
The tower is 28 m tall and its light is 58 m above sea level. The beam reaches roughly 19 nautical miles, guiding ships heading for the Lisbon approaches. The tower is faced in white tiles (azulejos), renewed in 2003.
How did it come about?
By 1523 oil lamps were burning at the hermitage of Nossa Senhora da Guia, built on land donated by Dom Luiz de Castro, to help sailors. In 1537 the brothers of the hermitage raised a tower where four or five oil lights were lit. The 1755 earthquake badly damaged it. The Marquis of Pombal then ordered a series of lighthouses along the coast, Guia among them, and the rebuilt tower was finished in 1761. Sources differ on the exact dating of the present structure, but all place it after 1755.
How do you get there?
From central Cascais it is a walk of about 2 km each way along the seafront road, or a short ride by bike or car. The lighthouse is best viewed from the outside, from the cape grounds; interior visits are not a standard attraction, so check current access with the local tourist office.
When should you visit?
Late afternoon works best, when low sun lights the white tower and the ocean turns gold at sunset. Wind on the cape can be strong even on warm days, so bring a light jacket.
What else is nearby?
Cabo da Guia lies on the Cascais coastal walking route. Beaches, the marina and rocky cliffs are close, and the cape looks out over the Atlantic.
