Ocna Mureş (Hungarian: "Marosújvár", German: "Miereschhall") is a town in Alba County, Romania, located in the north-eastern corner of the county, near the Mureş River, with a population of 15,526 inhabitants. The town is situated next to a large deposit of salt, mined in the past until the ceiling of the mines collapsed from water infiltration. Ocna Mureş has a chlorosodic products plant and a spa which uses the salty water from the former mines.
The spa is no longer running. The soda factory in town was purchased by an indian company. The majority of high school students attend either Liceul Teoretic Petru Maior or the 'Chemistry School,' where many are trained to later work for the factory in town. Exceptional students progress onto University in nearby Cluj. The downtown was relocated after the mine was flooded as the ground became unstable. Now this area is filled with more then 4 large, very deep lakes. The center of town is now at the base of a large hill, the 'banta.'
