Perchtoldsdorf Castle probably was laid out before 1000 AD, part of a chain of fortifications along the eastern rim of the Vienna Woods. One Lord Heinricus de Pertoldesdorf was mentioned in an 1138 deed, during the Babenberg rule. Their Perchtoldsdorf vassals continued to rule from the castle even when the Babenberg dynasty became extinct in 1246.
The conflict between the Habsburg emperor Frederick III and his younger brother Archduke Albert VI of Austria started an unstable period in the region. In 1446, many homes in the town were burned during the invasion of the Hungarian regent John Hunyadi. During this time, the castle was occupied by various rival forces, including mercenaries of King Matthias Corvinus from 1477 until about 1490, when Frederick's son King Maximilian I re-established Habsburg control over the area. This turbulent period interrupted the construction of the tower house (Wehrturm), the town's landmark with a height of 60 metres. The tower and other fortifications permitted a successful defense of the city against the Ottoman troops during the 1529 Siege of Vienna, while the surrounding area was devastated.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.
