Wartenstein castle was built around 1206 by Konrad von Zwiefalten. The castle is mentioned for the first time in 1208 and later owned for several families. In 1341 it was rebuilt and repaired by abbot Hermann II of Arbon. After the middle of the 16th century sources describe the castle dilapidated. The Abbey Pfäfers gave in 1586 the worthless site to the local residents as a quarry.
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.
