Pleterje Charterhouse is the only extant monastery of Carthusian order in Slovenia. The monastery was founded in 1403 by Count Hermann II of Celje, and its construction completed by 1407. In 1471 an Ottoman raid destroyed the buildings, which were reconstructed in a much stronger and more easily defensible manner.
After a long period of decline Archduke Ferdinand II of Inner Austria gave the monastery in 1595 to the Jesuits of Ljubljana. When the Jesuits were suppressed in 1772, Pleterje became state property. In 1839 it passed into private hands.
In 1899 the Carthusians reacquired the site and began construction of a new monastery, which was completed five years later. During World War II the charterhouse suffered severe damage when in 1943 it was set on fire by Communist partisans.
The charterhouse has remained a Carthusian monastery to this day. The buildings date from the second foundation in the late 19th century, except for the Gothic church, dedicated to the Holy Trinity, which survives from the earlier monastery.
The monks cultivate 30 hectares of land, mostly for fruit and honey, which they sell, and from which they also produce wine, fruit spirits (especially pear brandy), mead and beeswax candles.
The monastery accommodates a display of items from the collections of the Dolenjska Museum of local history, and on part of its lands stands the Pleterje Charterhouse Open Air Museum of typical Slovenian buildings. The paintings date from the 17th and 18th centuries, and are attributed to Flemish, French, Italian and German artists. They seem mostly to have reached Pleterje with refugee monks from Bosserville Charterhouse in Lorraine, who were given shelter in Pleterje in 1904.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
