Lagos is a town in southern Portugal's Algarve region. It’s known for its walled old town, cliffs and Atlantic beaches. Steep wooden steps lead to the sandy cove of Praia do Camilo. The nearby cliffs of Ponta de Piedade offer sweeping headland views and a lighthouse. Igreja de Santo António, an ornate 18th-century church, sits across from the Castelo dos Governadores, a castle with a baroque facade and watchtowers.
