The Saviour Monastery of St. Euthymius was founded in the 14th century, and grew in importance in the 16th and 17th centuries after donations by Vasili III, Ivan IV and the Pozharsky family, a noble dynasty of the region. Among the buildings erected during this period were the Assumption Church, the bell tower, the surrounding walls and towers, and the seven-domed Cathedral of the Transfiguration of the Saviour. The cathedral was built in the style of the Grand Duchy of Vladimir-Suzdal. Its interior contains restored frescoes by the school of Gury Nikitin of Kostroma, dating from 1689. The tomb of Dmitry Pozharsky lies by the cathedral wall.
The monastery also contains a prison, built in 1764, which originally housed religious dissidents. The prison continued in use during the Soviet period, and among its better known prisoners was field marshal Friedrich Paulus, who was incarcerated here for a time after his surrender at Stalingrad. The prison now houses a museum about the monastery's military history.
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.
