In 1635, 229 inhabitants died of the plague. After the remaining inhabitants prayed to St. Sebastian, the Black Death stopped. Since this time, every year St. Sebastian's Day is celebrated specially due to a promise of the inhabitants at that time.

In 1822, a large fire devastated the centre of Winklarn. Afterwards, the large rectangular (134 by 26 metres (440 ft × 85 ft)) market place was built.

In 1972, the former communities Muschenried, Haag, Schneeberg, and Pondorf were incorporated.
