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.

The Abbey of Saint-Etienne, also known as Abbaye aux Hommes ('Men"s Abbey'), is a former monastery dedicated to Saint Stephen (Saint Étienne). It is considered, along with the neighbouring Abbaye aux Dames ('Ladies" Abbey'), to be one of the most notable Romanesque buildings in Normandy. Like all the major abbeys in Normandy, it was Benedictine.
Lanfranc, before being an Archbishop of Canterbury, was abbot of Saint-Etienne. Built in Caen stone during the 11th century, the two semi-completed churches stood for many decades in competition. An important feature added to both churches in about 1120 was the ribbed vault, used for the first time in France. The two abbey churches are considered forerunners of the Gothic architecture. The original Romanesque apse was replaced in 1166 by an early Gothic chevet, complete with rosette windows and flying buttresses. Nine towers and spires were added in the 13th century. The interior vaulting shows a similar progression, beginning with early sexpartite vaulting (using circular ribs) in the nave and progressing to quadipartite vaults (using pointed ribs) in the sanctuary.
The two monasteries were finally donated by William the Conqueror and his wife, Matilda of Flanders, as penalty for their marriage against the Pope"s ruling. William was buried here; Matilda was buried in the Abbaye aux Dames. Unfortunately William"s original tombstone of black marble, the same kind as Matilda"s in the Abbaye aux Dames, was destroyed by the Calvinist iconoclasts in the 16th century and his bones scattered.
As a consequence of the Wars of Religion, the high lantern tower in the middle of the church collapsed and was never rebuilt. The Benedictine abbey was suppressed during the French Revolution and the abbey church became a parish church. From 1804 to 1961, the abbey buildings accommodated a prestigious high school, the Lycée Malherbe. During the Normandy Landings in 1944, inhabitants of Caen found refuge in the church; on the rooftop there was a red cross, made with blood on a sheet, to show that it was a hospital (to avoid bombings).
