Bełżec was a Nazi German extermination camp built by the SS for the purpose of implementing the secretive Operation Reinhard, the plan to eradicate Polish Jewry, a key part of the 'Final Solution' which entailed the murder of some 6 million Jews in the Holocaust. The camp operated from 17 March 1942 to the end of December 1942. The burning of exhumed corpses on five open-air grids and bone crushing continued until March 1943.
Between 430,000 and 500,000 Jews are believed to have been murdered by the SS at Bełżec. This makes it the third worst extermination camp, exceeded only by Treblinka and Auschwitz. Only seven Jews performing slave labour with the camp's Sonderkommando survived World War II; and only one of them became known, thanks to his postwar testimony submitted officially. The lack of viable witnesses who could testify about the camp's operation is the primary reason why Bełżec is so little known despite the enormous number of victims.
The physical evidence of the camp's existence was almost entirely erased before the war's end as a result of the German prolonged cleanup efforts. In the late 1990s extensive investigations were carried out on the camp grounds to determine precisely the camp's extent and provide greater understanding of its operation. Buildings constructed after the war on the camp grounds were removed. In 2004, Bełżec became a new branch of the Majdanek State Museum. New official monuments commemorating the camp's victims were unveiled.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
