The Viareggio lighthouse is a maritime lighthouse in the Ligurian Sea located at the mouth of the Burlamacca canal in Viareggio, near the port infrastructure.
The infrastructure was built by the Regia Marina in 1863 for the night lighting of the corresponding coastal stretch; the current appearance was given by a restructuring of the twentieth century. After the construction of the outer breakwater, later equipped with its own more modern lighthouse, this infrastructure limited its functionality to the internal area of the port-canal. Now no longer in use.
The complex consists of a circular section tower in white masonry 14 meters high, with an internal gallery, which culminates with a summit terrace on which the lantern of the metal lantern rests, also with a circular section. The tower rises at the north-western corner of a quadrangular-plan building, arranged on two levels and also in white masonry.
