Lake Brâncoveanu (Romanian: Lacul Brâncoveanu) is a natural salt lake in the town of Ocna Sibiului, Sibiu County, Transylvania, Romania. It is one of the many lakes of the Ocna Sibiului mine, a large salt mine which has one of the largest salt reserves in Romania.[1] The lake has the biggest salinity out of every lake in the mine and is one of Romania's most salty lakes.
The lake is named after Constantin Brâncoveanu, a ruler of Wallachia.
Lake Brâncoveanu is situated on the site of a salt mine that was in operation until 1699, when water infiltration caused it to be abandoned. In 1966, the water level of the lake had a sharp decrease of 11 m, because of the leakage of water through a crack produced in the salt wall in the underground lake adjacent to the Ignatius mine.
