the 20th century, the House of Schwarzenberg owned the town and the estate. The town slowly recovered and remained economically unimportant until the 19th century, when it became a district town. Until 1918, Třeboň – Wittingau (Wittingau until the end of the 19th century) was part of the Austrian monarchy (Austria side after the compromise of 1867), in the district with the same name, one of the 94 Bezirkshauptmannschaften in Bohemia. After the World War II, the first larger industry (clothing factory and large-scale agricultural production) was established in the town. In 1960, the Třeboň district was abolished and the town received spa status. Demographics Economy Třeboň is a tourist destination, and this is the area's major economic activity, along with agriculture, the spa industry and other services. The State Regional Archive for South Bohemia is based here, where genealogical studies about people born in the South Bohemian Region may be conducted. Digital images of parish registers and other genealogical records from the archive have been placed on the internet. The archive was held at the 15th-century Třeboň castle for many years, although a substantial portion was moved to the municipal offices in 2014.
