Hohnstein Castle is located on a hard sandstone slab, 140 metres above the Polenz valley and is the major landmark of the small town. It was probably built around 1200 or earlier as a Bohemian border fortress for the Margravate of Meißen to defend it against Saxony. In 1353 the castle went into the possession of the Bohemian nobleman, Hynek Berka z Dubé, whose coat of arms with crossed oak branches decorates the entranceway to the second courtyard. In 1443 the Berkas of Dubá lost the estate through exchanges and purchase, only mentioned for the first time under their name, to the Electorate of Saxony under Frederick the Humble, although it remained a Bohemian fief until 1806. The Wettins used it as a base for hunting and for salmon spearing (Lachsstechen).
In the succeeding centuries the castle acted alternately as a seat of administration (electoral Amt), a court and a prison. The original wooden structures were gradually replaced during the 17th and 18th centuries by the present stone buildings and even successfully withstood a Swedish siege in 1639.
After the dissolution of the Amt in 1861 the castle served as a men's correctional institute (Männerkorrektionsanstalt) and from 1919 as a juvenile prison.
In 1925 the mighty castle became a youth hostel. In the years 1933/34 a concentration camp was established here for so-called protective custody prisoners (Schutzhäftlinge), in practice 5,600 political prisoners. During World War II a prisoner of war camp was housed in the castle and, after the war it was a refuge for displaced persons. From 1949 it was extended to become the largest youth hostel in the GDR. In 1953 the National Science Museum for Geology, Botany, Zoology and Ecology of the countryside was established here. In 1997 the castle was turned into a Friends of Nature house and youth guest house, to which the museum belongs today.References:
Montparnasse Cemetery was created from three farms in 1824. Cemeteries had been banned from Paris since the closure, owing to health concerns, of the Cimetière des Innocents in 1786. Several new cemeteries outside the precincts of the capital replaced all the internal Parisian ones in the early 19th century: Montmartre Cemetery in the north, Père Lachaise Cemetery in the east, and Montparnasse Cemetery in the south. At the heart of the city, and today sitting in the shadow of the Eiffel Tower, is Passy Cemetery.
Montparnasse cemetery is the burial place of many of France's intellectual and artistic elite as well as publishers and others who promoted the works of authors and artists. There are also many graves of foreigners who have made France their home, as well as monuments to police and firefighters killed in the line of duty in the city of Paris.
The cemetery is divided by Rue Émile Richard. The small section is usually referred to as the small cemetery (petit cimetière) and the large section as the big cemetery (grand cimetière).
Although Baudelaire is buried in this cemetery (division 6), there is also a cenotaph to him (between division 26 and 27). Because of the many notable people buried there, it is a highly popular tourist attraction.
