Montansiedlung Colloredohaus, Imhof-Stöckl, Protected heritage building in Bad Gastein, Austria.

The Colloredohaus, also called Imhof-Stöckl, is a two-storey masonry building with a hipped roof and a surrounding hollow moulding, located in the historic mining settlement of Altböckstein in Böckstein, Bad Gastein. Its baroque window arrangement and a bell tower transferred from the former administrator's house (now Böckstein parish house) are visible. Above the entrance portal is a coat of arms stone of Archbishop Hieronymus von Colloredo dated 1782. A single-storey southern annex, the former gold washing plant built around 1750, has a high baroque hipped roof with two rows of dormers and a coat of arms stone of Archbishop Andreas Jakob von Dietrichstein dated 1750 on its eastern facade.

Altböckstein was laid out as a planned Baroque mining settlement from 1741 to 1745 and completed in 1764, after an avalanche disaster. The house served as the administrator's residence for the mining operations. A coat of arms stone above the entrance portal bears the name of Archbishop Hieronymus von Colloredo and the year 1782.

The name Colloredohaus comes from the coat of arms stone of Archbishop Hieronymus von Colloredo above the entrance portal, dated 1782. The building served as the administrator's house for the Altböckstein mining settlement, and its bell tower was moved here from the first administrator's house, today the Böckstein parish house.

The building stands in the mining settlement of Altböckstein in the Böckstein district of Bad Gastein, not in the town centre. The two-storey main house has a hipped roof with a surrounding hollow moulding; the single-storey southern annex, the former gold-washing plant, has a high hipped roof with two rows of dormers. Look for the coat of arms of Archbishop Hieronymus von Colloredo (1782) above the entrance portal and that of Archbishop Andreas Jakob von Dietrichstein (1750) on the east facade of the former washing building.

The single-storey south annex is the former gold-washing plant of Altböckstein, built around 1750 and used as a magazine from 1912. Its high baroque hipped roof carries two rows of dormers, and a coat of arms stone of Archbishop Andreas Jakob von Dietrichstein dated 1750 is set into the east facade of the former washing vat.
