The first development at Scicli was around the Castello dei tre cantoni at the top of San Matteo hill that overlooks the town. The Castello dei tre Cantoni is actually composed of two separate fortifications, the Castelluccio higher up and the Castellaccio at a lower level.
This was a defensive structure that, over the centuries, was enlarged and used first by the Arabs, then by the Normans and then later as a military outpost of the County of Modica. The current castle is dated to the 13th century although studies date its origins to the first half of the 12th century.
The Castle has a triangular tower, while to the north-east stands a large wall terminating in a quadrangular tower. The reason for having an unusual triangular tower is unknown, but thought to be symbolic (possibly related to the three points of Sicily itself) rather than a military function.

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
