Gross-Rosen concentration camp was a German network of Nazi concentration camps built and operated during World War II. The main camp was located in the village of Gross-Rosen not far from the border with occupied Poland, in the modern-day Rogoźnica, Poland.
At its peak activity in 1944, the Gross-Rosen complex had up to 100 subcamps located in eastern Germany, Czechoslovakia, and on the territory of occupied Poland. The population of all Gross-Rosen camps at that time accounted for 11% of the total number of inmates incarcerated in the Nazi concentration camp system.
KZ Gross-Rosen was set up in the summer of 1940 as a satellite camp of the Sachsenhausen concentration camp from Oranienburg. Initially, the slave labour was carried out in a huge stone quarry. In October 1941 the SS transferred about 3,000 Soviet POWs to Gross-Rosen for execution by shooting. Gross-Rosen was known for its brutal treatment of the so-called Nacht und Nebel prisoners vanishing without a trace from targeted communities. Most died in the granite quarry. In 1942, for political prisoners, the average survival time-span was less than two months.
At its peak activity in 1944, the Gross-Rosen complex had up to 100 subcamps, located in eastern Germany, Czechoslovakia, and occupied Poland. In its final stage, the population of the Gross-Rosen camps accounted for 11% of the total inmates in Nazi concentration camps at that time. A total of 125,000 inmates of various nationalities passed through the complex during its existence, of whom an estimated 40,000 died on site, on death marches and in evacuation transports. The camp was liberated on February 1945 by the Red Army.References:
Derbent is the southernmost city in Russia, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains connecting the Eurasian steppes to the north and the Iranian Plateau to the south. Derbent claims to be the oldest city in Russia with historical documentation dating to the 8th century BCE. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, Shirvan and Iranian kingdoms.
Derbent has archaeological structures over 5,000 years old. As a result of this geographic peculiarity, the city developed between two walls, stretching from the mountains to the sea. These fortifications were continuously employed for a millennium and a half, longer than any other extant fortress in the world.
A traditionally and historically Iranian city, the first intensive settlement in the Derbent area dates from the 8th century BC. The site was intermittently controlled by the Persian monarchs, starting from the 6th century BC. Until the 4th century AD, it was part of Caucasian Albania which was a satrap of the Achaemenid Persian Empire. In the 5th century Derbent functioned as a border fortress and the seat of Sassanid Persians. Because of its strategic position on the northern branch of the Silk Route, the fortress was contested by the Khazars in the course of the Khazar-Arab Wars. In 654, Derbent was captured by the Arabs.
The Sassanid fortress does not exist any more, as the famous Derbent fortress as it stands today was built from the 12th century onward. Derbent became a strong military outpost and harbour of the Sassanid empire. During the 5th and 6th centuries, Derbent also became an important center for spreading the Christian faith in the Caucasus.
The site continued to be of great strategic importance until the 19th century. Today the fortifications consist of two parallel defence walls and Naryn-Kala Citadel. The walls are 3.6km long, stretching from the sea up to the mountains. They were built from stone and had 73 defence towers. 9 out of the 14 original gates remain.
In Naryn-Kala Citadel most of the old buildings, including a palace and a church, are now in ruins. It also holds baths and one of the oldest mosques in the former USSR.
In 2003, UNESCO included the old part of Derbent with traditional buildings in the World Heritage List.
