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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
