In 1510, the mining lords and miners of the Gossensass-Sterzing mining court had a chapel built on the rock protecting the north-east side of St. George's Church as a symbol of the guild in honour of the miners' patron saint St. Barbara. The chapel is the work of the Sterzing master builder Adam Schaiter and has a two-storey structure with a square ground plan and polygonal chancel end. A Gothic pointed spire set at the corner completes the building at the top. A coloured Austrian shield is visible on the south-west side of the ridge turret. A double flight of steps leads to the first and second floors, to the lower and upper chapel. The basement houses a crypt, which is used as a mortuary chapel.
