The Porvoo Cathedral was originally made of wood. The first stone walls were built between 1410 and 1420 and in 1450 the church was expanded four meters towards east and six meters towards south.
The cathedral has been destroyed by fire numerous times; in 1508 by Danish and in 1571, 1590, and 1708 by Russian forces. On May 29, 2006, the outer roof collapsed after arson, however with the inner ceiling undamaged and the cathedral interiors intact. The Cathedral was reopened on 2 July 2008.
Porvoo Cathedral is situated in the middle of Porvoo well-preserved and beautiful old town, which is popular tourist attraction particurarly in summer season.
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.
