The Fortezza, the Italian word for fort, took hundreds of years for build, until the 1670's, to protect the city and its residents from pirates who were active in the area, especially because the legendary pirate Khir al-Din Barbarossa.
Indeed, the Fortezza of Rethymno has been fairly well preserved since its glory days. You can see the impressive fortress, spread to four towers and three gates. On the visit here you can see the antiquities of the place, the church and the mosque that remain here from the past residents of the fortress.
Archaeologists think that beneath the fortress lays the ancient Acropolis of Rethymno. From this point, they explain, was the place where the rulers controlled the state in antiquity.
Be sure to look at the surrounding views. The view is magnificent from the walls, towards the sea, the harbor, and the lighthouse, this is one of the more beautiful experiences in the city.
The main goal of the fortress was to protect the city of Rethymno and the Venetian regime, but when put to the test, the fortress failed to secure the locals from the Ottoman Turkish Empire who took control of the city without any particular setbacks.
It is interesting to note that the fortress hardly changed during the Turkish occupation, which began in 1646. Contrary to what was expected, there are no significant changes from that period.
It seems that actually around the 20th century, when many people began moving into the fortress, the fortress went through its biggest changes. In addition to the residential buildings built then, it held the regional prison and even a brothel at the time.
