Třeboň is a tourist destination, and this is the area's major economic activity, along with agriculture, the spa industry, and other services.
Třeboň was established around the middle of the 12th century. In 1366, the House of Rožmberk became owner of the estate. The period of greatest growth for the town dates to the second half of the 15th century when Petr IV of Rožmberk (1462–1523) began to seriously take care of the land. The district became famous as a fish pond farming area. From 1611 the Houses of Habsburg and Schwarzenberg were owners of the town and the estate.
