Covasna is a town in Covasna county, Transylvania, Romania, at an altitude of 550-600 m.
Known as the "town of 1,000 mineral springs," Covasna is famous for its mineral waters. Each spring has a different mixture of minerals, chiefly carbon dioxide, sulfur, and ammonia. Its name is derived from the Slavic word Cvaz, meaning sour, referring to the taste of its mineral waters.
