Description

Flogberget was named after an old Swedish legend. Floga is sea fire, a phosphorescence of microorganisms in the water, which according to the legend comes from the mouth of a flying dragon. Many people believed that floga is a sign for a rich seam of ore.

The mining area Flogberget has about 15 abandoned mines, originally opened during the 16th century. The mines were located on a hilltop and drained by adits to the surrounding foreland. This was fortunate for the mining, as this simple and old technique made drainage pumps obsolete.

During the times three different mining methods were used here. The oldest method used fire to make the rock brittle. Huge piles of wood were erected in front of the rock face and burnt. The heat caused the rock to expand until it cracked by the pressure and the brittle rock and ore could easily be removed. The miners used crowbars and sledge hammers. During the 18th century gun powder was introduced, later replaced by dynamite. This method was much more effective and increased the mined ore. And the third mining technique was the introduction of electricity during the 20th century. A crusher and an ore-dressing plant were installed, making the hard work easier and increasing production.

The modern machines crushed and separated the coarse ore. The fine-grained dressed ore was mixed with water and compressed into small pieces by a brick press. A 50m long furnace turned those pellets into briquettes which were carried to Hagge station with a cable-way and by rail. There the ore was smelted in a blast furnace. This method was invented here by Gustav Gröndahl.

The Stora Flogbergsgruvan (Old Flogberg Mine), a huge open cast mine, is today flooded. It is the starting point of a mining trail which leads to the still dry open-cast mines nearby which are linked by tunnels. The Nordvall gallery is a former mine tunnel open to the public. Inside is a multimedia display. At Flogbergsspelet, a tour with actors in period costumes dramatizes the time when the mine still worked. Those tours take place weekly during summer and are very popular, especially among children. For children there is also a small theme park where they can work in the forge and with wrought iron.
