One of the richest iron ore deposits at Norberg is Mossgruvan, where the mining museum is situated today. The visitor is given an idea of how it was to work and live by a mine more than a hundred years ago. The correct name is Risbergs konstschakt and the building was raised in 1876 over a 114 metre deep mine shaft. The shaft was originally sunk in the18th century.
A very important function of the shaft was to drain the mine. From the shaft it was possible to keep several adjoining pits free from water. The pump equipment was operated using power transmitted from a water wheel by means of a ”stånggång”, a long wooden construction.
The old pumping station has been restored. Visitors are today shown how water is pumped up from the mine. They can also look down the mine shaft.
Apart from the pumping station, a cable operated lift car to carry the miners as well as a canteen, a small foreman’s office and a forge are shown in the pit head building. Visitors can see the tools used by the smith and the old machine used to plane wood, still in working order. A visit to the mining museum may be combined with a tour of Mossgruveparken, a museum park with a signposted walk leading between the old water filled mine holes.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
