The squat round tower behind the seafront is the oldest building in Laigueglia, raised in 1564 as part of the Ligurian coast's network of anti-corsair watchtowers. The structure is plain — a few storeys of dressed stone, no decorative work, narrow windows for muskets — and it was designed for function rather than show. It stood watch for two centuries against North African pirates and, when their raids stopped, was eventually abandoned and absorbed into the surrounding houses.
The tower is not open to visitors but is freely visible from the surrounding lanes. It is best seen from the small square at the seaward end of Via Genova, looking up between the houses. A useful pause on any walk through the old quarter.
