News server Denik.cz reports that the State Regional Archive (SOA) in Třeboň, Czech Republic has released on its website its archival collection of digitalized documents about the WWII-era concentration camp called the Zigeunerlager (in Czech, Cikánský tábor) at Lety; the digital collection was created in collaboration with the Institute of the Terezín Initiative in Prague as part of a project called the "Database of victims of the national socialist persecution of 'gypsies‘". "Several years ago we agreed with the Institute of the Terezín Initiative in Prague that we would like to make this collection publicly accessible as part of a project called the "Database of victims of the national socialist persecution of 'gypsies‘" supported by Bader Philanthropies," the director of SOA Třeboň, Václav Rameš, told Denik.cz.     

"The Institute digitalized this collection and experts from our archive then adapted it for our conditions," the director said, adding that the archival documents provide basic information about the creation and existence of all of the camps serving different purposes and of different levels of significance that appeared on the territory of Lety municipality, especially between 1940 and 1943, as well as up until 1945, when the Second World War ended. "There are, for example, lists of the gendarmes ordered to serve at the camp and above all there is documentation about those imprisoned there," the director said.
