Ursu Lake , a natural monument, is a protected area (natural reservation, mixed type) located in Mures County, on the administrative territory of Sovata. Lake Ursu was formed with the collapse of a salt mine, later filled with water from the streams that descend from the nearby slopes.
The salt massif near the lake is covered with a clay layer on which grow several species of woody plants (oak, oak, spruce, beech, pine, wild cherry, blood, hawthorn, aspen, forest apple, hazelnut, ash, maple) as well as grassy species, tooth of which: lady's slipper (Cypripedium 24calceolus) or lily of the valley.
Salina Praid
The first salt mines are attested from the time of the Romans, but the mine from Praid is documented from 1200, and the intensive exploitation is made from 1700.
Volker Wollmann in his monograph on mining emphasizes the presence in the immediate vicinity of the salt deposits, each time, of a Roman fortification. The Romanian camp Praetoria Augusta from Inlaceni defended the salt mines from Praid.
In 1980, a treatment base was opened in the salt mine.
