A 15th-century house which adopted different architectural styles in later centuries until it evolved into its current amalgamation of Gothic and Baroque facade. The Rococo stucco decorations that look like icing on a cake were added in the early 18th century, and these bows, window frames, oriels, masks, sculptures and shells are what makes this building unique. The architecture helps to capture a maximum of sunlight, which is sparse in the Alps. The last major construction took place in 1732 by Anton Gigl, after which the building was renamed to Sebastian Helbling who owned it at from 1800 until 1827.
