Lazurová Mountain Nature Reserve
Lazurová hora (Lazurová Mountain, derived from the blue lazurite mineral) is 650 metres high and it lies near the village of Horní Kramolín. A brook known as Kosí potok (Blackbird Brook) winds around the southern and eastern slope of the mountain. You can get to the mountain by cycle route No. III from Mariánské Lázně. After about 500 metres from Bukové údolí (the valley is commonly known as Buchtál) in the direction of Dolní Kramolín, you will reach a left turn leading across a bridge. Turn left and after crossing the bridge continue to the Tabákový mlýn (Tobacco Mill). In front of the mill, you will find a board with information about two ancient lindens standing by the mill gate, which have been declared monument trees. Despite being deserted, the mountain is quite romantic. It was declared a nature reserve, unfortunately with no decent road or path leading to it. An old forest path leads to its top from the Tobacco Mill, however, it is suitable only for very experienced bikers. The mountain is also accessible from Výškov but the area is interwoven with many field paths and you could get lost quite easily.
Lazurová Mountain belongs among significant geological sites. In 1542, Count Šlik owned a mine with a deep drift into the mountain. In its time, it was the only mine in Bohemia where cobalt and nickel ore was extracted. Cobalt ore was used for producing a blue (lazurite) colour, which gave the mountain its peculiar name. In the 16th century, silver was mined by the Premonstratensian monks from Teplá and the Šlik family. Dozens of drifts, most of which are currently caved-in, lead into the entrails of the mountain. Major mines include Saint Barbora, Eliáš, Erasmus and Bohatá útěcha (Rich Solace). Moreover, a breeding place of the common bat was discovered in the Věra adit and it has been included in the European network of Sites of Community Significance. The eastern part of the mountain conceals a large cave-like drift, which is known as Mramorová jáma (Marble Pit).
Pink marble or limestone was extracted from the pit. It should be mentioned that traces of a castle almost unmentioned in historical documents were discovered on the mountain a few years ago.
