The Bollerup estate was first time mentioned in 1130. The castle was built in the end of 15th century. The present living quarters were built in the 1840s. It lies on an islet and is surrounded by a moat.
Bollerup has been owned by several families like Thott, Gjöe and Rantzau. Today it houses the Bollerup Agricultural Institute. Guided tours of the fort, grounds, stables and church are available during the summer.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
