Naillac Tower (Pyrgos Naillac), formerly known as Tower St. Michael, which no longer exists today, was built by Grand Master Philibert de Naillac before the development of artillery guns, and adopted the square well medieval fortifications.
Naillac tower was an imposing building 46 m high, much higher than the other towers of the enclosure. The four corners of the terrace, there were four small turrets round, and in the middle of the platform stood another round, octagonal and smaller.
Naillac tower, overlooking the port of Rhodes was severely cracked and shaken by two earthquakes in the nineteenth century, the second in October 1856, and was perhaps destroyed because it threatened to collapse on ships in the harbor .
You can still see the bridge leading to the tower and walls built around by Pierre d'Aubusson .
