Slovenia

Slovenia is live on Travelog with one city, Idrija, whose mercury-mining heritage was inscribed by UNESCO in 2012 as part of a shared listing with Almadén, Spain, recognizing the two largest mercury mines in the world. Mercury was first discovered in Idrija in 1490, and Anthony's Shaft, the mine's oldest section dug just a decade later in 1500, remains open to visitors today.

Idrija's story is genuinely international, a shared UNESCO listing with Almadén in Spain, recognizing the two largest mercury mines that ever operated anywhere in the world, one in each country. Its landmark page is live now.
