The first mention of a castle in Frymburk's area is from 1198. The first written mention of the settlement is from 1270. Until 1302, it belonged to the
Vítkovci lords of
Český Krumlov, and after their extinction it was acquired by the
Rosenberg family. It 1379, it was first referred to as a town. From the 16th century on, Frymburk had its own brewery. In 1598, Frymburk had already 118 houses. In 1620, it was acquired by
Lords of Bucquoy. During the
Thirty Years' War, the town was destroyed and burnt down by
Swedish troops. Another disaster occurred in 1856 when a fire destroyed the town square and 54 houses. The town was relatively progressive, as could be seen by the installation of streets lights as early as 1881 and the introduction of a
telegraph station in 1884. In 1918, Frymburk became part of the newly established
Czechoslovakia, and its population had German majority. In 1938, it was annexed to Germany. After the
World War II, the German population was
expelled and Frymburk was resettled by
Czechs,
Slovaks,
Romanians and
Volhynian Czechs. The most significant change at Frymburk occurred in 1959 when the Lipno Reservoir was built and it became a recreation area. ==Demographics==
