Grolman Bastion was part of the Königsberg fortification system. Named after General Karl Wilhelm von Grolman, it was finished in 1851. It was strengthened with casemates and caponniers inside its wall and consists of lesser Oberteich and Kupferteich Bastions. The Bastion was considerably damaged by Soviet Army in the World War II. There was a vegetable storehouse in the Bastion during the Soviet time. Nowadays this fortress memorial is under reconstruction.
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.
