The St. Mary's Church in Sønderborg is located on a hill and is a very iconic for the city. In the Middle Ages there was a leper colony on a hill just outside the city. It was named after Saint George and around 1300 the chapel of this leper colony stood in the place of the present St. Mary's Church. After the old parish church of the city, the St. Nicholas Church, was demolished around 1530, the Saint-George chapel became the new main church. Towards the end of the 16th century, John II, Duke of Schleswig-Holstein-Sonderburg commissioned the enlargement of the building in order to make it suitable for the function of the parish church of his city.
In 1595 a start was made on the partial demolition of the old church and the construction of the new church. Only parts of the old medieval church remained. From the medieval church, a medieval wooden wall cupboard dating from about 1400 remained. The solemn inauguration of the new parish church took place just before Christmas in 1600. In 1649 the George Church was renamed as the Mary Church.
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.
