Ohlsdorf Cemetery is the fourth-largest cemetery in the world. Most of the people buried at the cemetery are civilians, but there is also a large number of victims of war from various nations. It was established in 1877 as a non-denominational and multi-regional burial site outside of Hamburg. The cemetery has an area of 391 hectares (966 acres) with 12 chapels, over 1.5 million burials in more than 280,000 burial sites and streets with a length of 17 km.
During World War I over 400 Allied prisoners-of-war who died in German captivity were buried here in, as well as sailors whose bodies had been washed ashore the Frisian Islands. In 1923 the remains of British Commonwealth servicemen from 120 burial grounds in north-western Germany were brought to Hamburg. Further dead Commonwealth soldiers of World War II and of the post war period were buried here too.
There are six memorial sites for the victims of the Nazi era. The remains of some 38,000 victims of Operation Gomorrha, the bombing campaign that took place from July 24 to August 3, 1943, lie in a cross-shaped, landscaped mass grave.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
