"Burg Griesbach" is first mentioned in a document from around 1076. The place was part of Landshut. It was raided and destroyed by an army from the
Electorate of the Palatinate in 1504, only to be re-erected soon afterwards. In 1778/79 Griesbach was occupied by Austrian forces. As part of the Dukedom
Bavaria, (official name) became more independent. In 1953 it was officially turned into a town (Kleinstadt). The Bavarian reform of 1972 merged the municipalities of Karpfham, Parzham, Reutern, St. Salvator and Weng. The discovery of hot springs in 1972/73 lead to a new orientation as a spa town. ==Mayors==
