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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
