Barbarakapelle, Karsdorf, Gothic chapel ruin in Karsdorf, Germany

Barbarakapelle is a late Gothic chapel ruin above Oelsa on the Clausenweg in the Dippoldiswalder Heide, on the Rabenau–Dippoldiswalde pilgrimage loop. Its walls stand 13 metres wide and 16 metres long, and the spring of the Barber stream rises on the site. The choir has a pointed-arch window inserted in 1882.

The chapel is first recorded in the 1495 register of the Diocese of Meissen and was built by Sigismund von Maltitz, lord of Dippoldiswalde, who died in 1525. It served pilgrims walking from Dippoldiswalde to Altzella. One account holds that Bishop Johann VIII von Maltitz, the builder's brother, had it destroyed in 1539 out of concern over secret gatherings of Reformation followers; another says it fell in 1630 during the Thirty Years' War, since it still appears as a chapel on Matthias Öder's 1630 map.

The chapel is dedicated to Saint Barbara, the patron saint of miners in German-speaking regions. Visitors today can still feel how closely faith and mining work were tied together in this part of Saxony.

The ruin is reached by forest paths that pass by other historical spots in the area, making it easy to combine with a longer walk. Sturdy footwear is a good idea, as the paths can be muddy or uneven depending on the season.

The chapel stands on the headwaters of the Barber stream, which joins the Oelsabach after about 530 metres near the forest stadium. A legend credits this spring water with healing powers; in 1910/1911 it was collected in wells and fed into the drinking water supply of Rabenau and Oelsa.
