Torre di Porto Palo, Sixteenth-century coastal tower in Porto Palo, Menfi, Italy.

Torre di Porto Palo is a coastal tower built in 1583 in the fishing village of Porto Palo, in the territory of Menfi in the province of Agrigento, Sicily. It stands among the boats and beaches of the village, a short distance from the sea it was meant to watch.

The tower was built in 1583 as part of Sicily's coastal defense network against sea raiders. It served as a strategic fortification to protect nearby settlements from pirate attacks.

The tower stands in the fishing village of Porto Palo, in the territory of Menfi, where it is a landmark of the small borgo. Its name comes from the locality itself, a coastal spot in the Agrigento province of Sicily. Visitors see it as part of the village seafront rather than as an isolated monument.

Entry to the tower is through a door on the first floor facing inland, away from the coastal side. The interior features narrow passages and low ceilings designed to impede movement during defensive situations.

The tower displays remarkably thick outer walls that are significantly heavier than the inner walls, a deliberate engineering choice. This uneven distribution of wall thickness was a proven technique to reinforce the structure against cannon fire.
