This building in the middle of the village, below the road, was built in the Baroque style in the second half of the 18th century on the site of the abandoned Eleonóra Shaft.
All the mine maps were drawn and all the surveying work connected with mining was carried out here.
It was built without a single metal component so as not to interfere with compass measurements taken against a precisely surveyed meridian. The Mine Surveying Office, which was based in the building, was closed in 1921.
