Risiera di San Sabba is a five-storey brick-built compound located in Trieste, that functioned during World War II as a Nazi concentration camp for the detention and killing of political prisoners, and a transit camp for Jews, most of whom were then deported to Auschwitz. SS members Odilo Globocnik and Karl Frenzel, and Ivan Marchenko are all said to have participated in the killings at this camp. The cremation facilities, the only ones built inside a concentration camp in Italy, were installed by Erwin Lambert. Today, the former concentration camp operates as a civic museum.
The building was erected in 1913 and first used as a rice-husking facility (hence the name 'Risiera'). During World War II, German occupation forces in Trieste used the building to transport, detain and exterminate prisoners. Many occupants of Risiera di San Sabba were transported to the German Nazi concentration camp at Auschwitz-Birkenau in Occupied Poland. Historians estimate that over 3,000 people were killed at the Risiera camp and thousands more imprisoned and transported elsewhere. The majority of prisoners came from Friuli, the Julian March and the Province of Ljubljana.
After the war, the camp served as a refugee center and transit point. In the 1950s, many people, especially ethnic Italians fleeing then communist Yugoslavia, passed through the camp, not to mention Croats and Russians, whose home was San Sabba, San Sabba Annex, Opicina, Gesuiti for more than three years before they were able to emigrate elsewhere.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
