Torre Mulinazzo, Coastal defense tower in Cinisi, Italy

Torre Mulinazzo is a coastal defense tower inside the Falcone e Borsellino Airport at Punta Raisi, in the municipality of Cinisi. Its truncated-conical base was incorporated into a truncated-pyramidal structure, with two projecting corner platforms in tuff blocks. The first floor is a single square room about 5.80 m per side with a barrel vault about 5 m high, a large stone-framed fireplace on the north wall and a wall cupboard on the south wall.

Construction began in 1552 under Viceroy Juan de Vega as part of Sicily's coastal defense system. In 1578 the architect Tiburzio Spannocchi ordered structural modifications that raised the building and altered its original design.

The tower's name comes from the Punta del Mulinazzo on the Cinisi coast where it stands, now inside the Falcone e Borsellino airport grounds. Its signalling role has come full circle: the airport's own lights are mounted on the summit of the terrace. A tubular iron staircase, not the masonry stair refused in 1584, leads to the first floor.

The tower sits on state property managed by aviation authorities, which limits public access to the interior. Visitors can observe the exterior from nearby paths and coastal areas, but cannot enter the building.

The tower was originally built with a truncated cone-shaped base but was later transformed into a square structure. The original foundation was cleverly kept and incorporated into the new shape during this redesign.
