Târgu Ocna Salt Mine, located in Bacău County, is one of the oldest and most important salt extractions in Romania, with a history dating back to the Daco-Roman period. Modern exploitation began in the 14th century, and today the mine functions as both an industrial center and a major balneary destination. The tourist mine is located in the "Trotuș" level, at a depth of 240 meters, offering generous spaces with heights of up to 8 meters. A unique element is the Saint Varvara Church, located underground and built entirely of salt, providing a distinctive religious atmosphere. The saline air in the galleries is recognized for its therapeutic properties in treating respiratory conditions such as asthma and bronchitis. In addition to the treatment base, the mine features sports fields, a salt museum, and a saltwater lake. The extraction plays a central role in the region's economy, exporting high-quality salt to numerous countries.
