Idrija Mercury Mine

The Idrija Mercury Mine in Slovenia is a UNESCO World Heritage site and one of the most fascinating industrial heritage attractions in Europe. Discovered in 1490 by a local tub maker, the mine quickly became one of the world’s largest sources of mercury, shaping the town’s fortunes and leaving a lasting mark on global industry and science. For over 500 years, Idrija’s miners extracted mercury from deep beneath the earth, creating a unique community with its own traditions, legends, and crafts.

Visitors to Idrija can explore this rich history through guided underground tours of the mine, where you’ll walk the same tunnels that generations of miners once worked. Knowledgeable guides share stories of the mine’s discovery, the challenging conditions faced by workers, and the technological innovations that made Idrija famous. Above ground, the Gewerkenegg Castle houses the Idrija Municipal Museum, which offers insights into the daily life of miners and their families, including the town’s renowned lacemaking tradition.

A highlight of any visit is the chance to see the Idrijska rudarska hiša, a preserved miner’s house from the early 20th century, and to sample local specialties like Idrija žlikrofi, a traditional dumpling dish. Admission prices for experiences range from €17 to €92, depending on the activity, and guided tours are available year-round. The Idrija Mercury Mine is a must-see for anyone interested in history, engineering, or the enduring spirit of Slovenia’s mining communities.
