St. Florentina’s castle was built on the place of so called Domus, the type of old Roman house occupied by the upper classes. Domus represented not only the centre of wine-making in the region but also one of the first centres for ancient settlements. In the 11^th century the building functioned as fortification in order to defend from frequent pirates’ attacks. Remains of this building are still a part of St. Florentina’s Castle.
