Blens Castle

Blens Castle stands at a height of 205 m above sea level on the eastern edge of Blens, a town quarter of Heimbach above the River Rur in the county of Düren, in the German state of North Rhine-Westphalia.
As early as the start of the 12th century there is a seal of a certain Johannes de Blens. In 1380 the male line of the de Blens family died out. Through marriage the hill castle went to the von Berg family, who died out in 1550. Agnes of Blens received the estate through inheritance. As a result of marriages the castle went via the Lord Raitz von Frentz in the 18th century to Lord Beissel of Gymnich. Again through marriage the castle went via George Anthony Beissel of Gymnich in the 20th century to the House of Abercron, who own and live in it today.
