History Mercury was discovered in Idrija (known as Idria under Austrian rule) in the late 15th century (various sources cite 1490, 1492, and 1497). To support the mining activities, Gewerkenegg Castle was constructed between 1522 and 1533 by the mine owners. Mining operations were taken over by the government in 1580. The mineral idrialite, discovered here in 1832, is named after the town.

Church The parish church in the town is dedicated to Saint Joseph the Worker and belongs to the Diocese of Koper. There are three other churches in Idrija, dedicated to the Holy Trinity, Saint Anthony of Padua, and Our Lady of Sorrows.
