Azeda Lighthouse.

Seen from Travessa Nova de Sintra, Setúbal, this 31 metres high lighthouse stands since 1940 on top of a hill - now a residential area. There is a smaller automatic one by the riverside, close to the fishing dock. Boats and ships proceeding from the sea must enter the estuary of River Sado in such a way that the lights of both lighthouses fit in the same vertical line.
