The Santa Marta Lighthouse Museum is a working lighthouse and museum in the Santa Marta fort in Cascais, opened in July 2007 as the first lighthouse museum in Portugal. The lighthouse was first lit in 1868 and still guides ships into the bay of Cascais.
The architects Francisco and Manuel Aires Mateus designed the conversion, and the Portuguese Navy's Lighthouse Directorate supervises the light.
