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 castle of La Iruela, small but astonishing, is located on the top of a steep crag in Sierra de Cazorla, Segura y Las Villas Natural Park. From the castle, impressive views of the surrounding area and of the town can be enjoyed.
The keep dates from the Christian era. It has a square base and small dimensions and is located at the highest part of the crag.
There are some other enclosures within the tower that create a small alcázar which is difficult to access.
In a lower area of the castle, protected with defensive remains of rammed earth and irregular masonry, is an old Muslim farmstead.
After a recent restoration, an open-air theater has been built on La Iruela castle enclosure. This theater is a tribute to the Greek and Classic Eras and holds various artistic and cultural shows throughout the year.
The first traces of human activity in La Iruela area are dated from the Copper Age. An intense occupation continued until the Bronze Age.
Originally, La Iruela (like Cazorla) was a modest farmstead. From the 11th century, a wall and a small fortress were built on the hill to protect the farmers.
Around 1231, don Rodrigo Ximénez de Rada, Archbishop of Toledo, conquered La Iruela and made it part of the Adelantamiento de Cazorla. Over the Muslim fortress, the current fortress was built.
Once the military use of the fortress ended, it was used as cemetery.
