Frias castle origins date back to the 9th century, when Alfonso VIII repopulated the valley to reinforce the border between Castile and Navarre. The historic quarter preserves its medieval atmosphere, and urban layout.
On the tallest, most rugged end of a hill, the castle of the Duke of Frías stands, with its beautiful and well-kept mullioned windows, and 13th-century Romanesque capitals. In the city centre we must point out the church of San Vicente, whose Romanesque main front was taken to New York after the tower fell in 1904, and the convent of Santa María de Vadillo, founded at the beginning of the 13th century.
Near the town, crossing the Ebro river, we see a gorgeous medieval bridge, with a defence tower that dates from the 14th century.
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.
