pure mercury in the mine (Idrija, Slovenia).
cinnabar ore (mercury sulfide, HgS).

Antonijev Rov (Anthony Main Tunnel) is a section of the world's second-largest mercury mine. The mercury was found in form of red cinnabar ore (mercury sulfide, HgS), which contains a high amount of mercury. Sometimes mercury is found in its pure form. Natural deposits of mercury are rather rare, and it is not necessary to burn this mercury as it is already pure. But unfortunately it is also very dangerous for the miner, as mercury slowly evaporates, even at the low temperatures of the mine, and so there is always mercury in the air which causes a dangerous poisoning. The miners very often got this poisoning which meant brain damages, muscle damages, loss of hair and teeth and heavy pains. Mercury is not secreted by the body so this poisonings were lethal in all cases.

The tour through the mine starts with an introductory slide show about the geology and the history of the mine. It is available in several languages. Then the visitor gets a green and black overcoat and a helmet. Equipped like that the Antonijev Rov is entered through one of the oldest preserved mine entrances in the world. It was dug in 1500, only a decade after the discovery of the mercury. The mine itself shows mining tools from 500 years of history, like the Kamst, a 200 year-old mine pump, driven by water. There is also the mine chapel Chapel of the Holy Trinity from the 18th century. The miners said a prayer in front of the statues of the patrons St. Achacius and St. Barbara before entering the mine down Attems’ Shaft.

The mine has a lot of nice minerals, cinnabar, metacinnabar, epsomite and idrialite. Idrialite (C22H14) was named after the town as it was first described in Idrija, its type locale, in 1832. The brown, yellow or green crystals are rather small and only visible with a magnifying glass, but they start to fluorescent in green or blue under ultra-violet light. But most impressive are still the drops of pure mercury which can be seen on the wall in crevices and cracks. They are not fully natural, but a result of a mine fire, which heated the cinnabar above 356.7 °C and thus the mercury was vaporized. The poisonous mercury gas killed many miners but when the mercury condensed it formed those drops.

In its heyday this was the world's largest mercury mine. Today it has been re-opened for visitors. The underground tour begins in the changing rooms where the miners used to gather before descending into the depths. Here you will be shown a multi-vision slide presentation on the origin of one of the most famous mines in the world, the exceptional geological structure of the ore deposit, as well as the development of the town and the mine through the centuries. After changing into the classic miner's costume - a green / black overcoat and helmet, you will be sent off into the underworld with the hearty miner's greeting Sreéno or Good Luck!

Displays include mining activities though five centuries, and a visit to the Mine Chapel of the Holy Trinity, You will also encounter globules of the only liquid metal which is oozing out of the bright red cinnabar ore.

Children will enjoy the encounter with the teasing pit elf. The descent into the deeper parts of the mine, with sound of rumbling of the mining machinery will make this a trip to remember. A circular route leads one back to the entrance. Walking boots are recommended.
