The Azeda Lighthouse went into operation on 6 June 1940 at the Quinta da Azeda in Setúbal, in Setúbal District, Portugal. Initially the light was mounted in a hut on a hill but new housing construction made it difficult to see and in 1996 a 31-metre tall cylindrical tower was constructed. The lighthouse is situated about 3 kilometres inland. In addition to supporting the light, the tower also functions as a water tower for the town of Setúbal.
