Built in the 12th century by Pedro Álvarez de Soutomaior it is one of the most important castles in Southern Galicia. Its origins can be traced back to the reign of Alfonso VII, when a military construction was built in a strategic location in the town of Soutomaior. On a hill at 119 metres above sea level at the bottom of the Ría de Vigo, the castle was near the coast but protected against the sea incursions of the Normans, the Turkish or pirates. It also controlled the communications from north to south, and dominated the valley of the Verdugo River, from its confluence with the Oitavén River to its mouth.
In the 15th century, the defensive tower was turned into a two-walled complex. At that time, the castle was closely linked to Pedro Álvarez de Sotomayor, popularly known as Pedro Madruga, who held the title of Count of Camiña, Viscount of Tui, and Mariscal of Baiona. There seems to be evidence that Cristopher Columbus and Pedro Madruga were the same person, since they had friends and rivals in common, and about one hundred places discovered in the New World were renamed with place names from As Rías Baixas.
Over history, Soutomaior was the centre of feudal power, the setting of many battles, and the summer residence of the noble families. Today, it is a historic site open to the public with a garden recognised as an International Garden of Excellence. The current magnificence of the building has been the result of several renovations and alterations.
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.
