Buildings at the site of Somma Lombardo Castle date from the 9th century and the fortress from the 13th century. In 1448, the brothers Francesco and Guido Visconti, took refuge in this town and castle from the forces of the Ambrosian Republic. They divided the landholdings and portions of the castle. The fortress has been amalgamated from adjacent residences, all once surrounded by a single moat. From the brother Francesco, who owned the newer portion of the castle, descend the Visconti di San Vito; while from Guido, who owned the lower and older portions of the castle, descend the Visconti di Modrone.
The San Vito castle contains frescoes attributed to the school of Camillo Procaccini and an altarpiece by Cerano. The castle also has an extensive collection of barber plates.
Parts of the castle are used for private events and open for guided tours.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. 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.
