Directorate of Lighthouses, Portugal, Maritime navigation authority in Paço de Arcos, Portugal
The Directorate of Lighthouses is a maritime authority based in Paço de Arcos that manages 47 lighthouses spread across mainland Portugal, the Azores, and Madeira. These structures provide navigation guidance and safety support through maintained infrastructure and operational systems.
The Portuguese Navy took control of the lighthouse network in 1892, establishing a unified approach to maritime safety. The Directorate was formally created in 1924 as an independent authority to continue this management.
The headquarters and the Santa Marta lighthouse museum in Cascais display exhibits about maritime navigation and how these structures operate in practice. Visitors can see historical navigation methods and understand the role these towers played in guiding ships.
Visitors can access 28 lighthouses on designated days, exploring these structures with professional guidance and safety supervision. It is helpful to check which locations are open at specific times, as availability varies depending on maintenance schedules and seasonal conditions.
About one-third of the managed lighthouses are open to visitors, offering insight into the daily operations of these isolated structures. Many towers still function actively, sending light signals at night to guide ships safely along the coast.
