At the end of the 13th century, Schönberg received market rights from the Counts of Hals. The Schönberg market belonged to the Rentamt Straubing and the Bärnstein District Court of the Electorate of Bavaria. Schönberg owned a market court with magistrate's own rights. Towards the end of the Thirty Years' War, in 1648, it was plundered twice by Swedish troops. In 1742, during the War of Austrian Succession, the Pandours plundered the town. Since Schönberg was not connected to a railway line, it was preferred in other respects: On July 1, 1908, the first motor postal car of the Passau-Schönberg postal motor car line was welcomed. Initially, there were two trips a day in each direction. The yellow-painted postal buses had 35 hp and reached a speed of 15 km/h. Just two years later the line was extended to Grafenau. Towards the end of the Second World War, the parish church and large parts of the market were destroyed. On January 1, 1971, as part of the local government reform, the community of Hartmannsreit joined Schönberg, and on May 1, 1978, the communities of Eberhardsreuth and Kirchberg also joined. On November 1, 1983, Schönberg received the title of a state-approved climatic health resort.
