The guided tour of Castro will begin with a visit of the Mother Church dedicated to the Madonna of the Annunciation.
The church was erected on a Greek temple. Of Romanesque design, the interior is characterized by a high altar in Baroque style and numerous paintings such as the Madonna of the Annunciation, protector of the village.

Following the tour, you will continue in the narrow streets of the historic center until you get a suggestive view of the sea and its Aragonese castle built on the remains of the oldest Byzantine fortress.
The castle has a rectangular plan with four corner towers. Entering, there will be a courtyard formerly used to store agricultural products that were marketed, and a large scale, now disappeared, with which you accessed the upper floors.
In the courtyard, you'll also find the doors of the rooms on the ground floor.

Inside, visit the Antonio Lazzari Civic Museum with its permanent archaeological exhibition “Castrum Minervae: between Greeks and Messapi,” which will allow you to admire the numerous and various finds from recent excavation campaigns in the area of the historic center.
