The Rundetårn (Round Tower) is a 17th-century tower located in central Copenhagen. One of the many architectural projects of Christian IV, it was built as an astronomical observatory. It is most noted for its 7.5-turn helical corridor leading to the top, and for the expansive views it affords over Copenhagen.
The tower is part of the Trinitatis Complex which also provided the scholars of the time with a university chapel, the Trinitatis Church, and an academic library which was the first purpose-built facilities of the Copenhagen University Library which had been founded in 1482.
Today the Round Tower serves as an observation tower for expansive views of Copenhagen, a public astronomical observatory and a historical monument. In the same time the Library Hall, located above the church and only accessible along the tower's ramp, is an active cultural venue with both exhibitions and a busy concert schedule.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.
