The Silver Underworld: Anthony’s Main Road (Antonijev rov)
Idrija is home to the world’s second-largest mercury mine, a site so significant it earned its place on the UNESCO World Heritage list. The heart of this subterranean world is Anthony’s Main Road (Antonijev rov), the oldest preserved entrance to the mine dating back to 1500. Walking through these tunnels, you aren’t just a tourist; you are retracing the steps of generations of miners who extracted liquid silver from the earth.
In 2026, we are celebrating a special 5-year jubilee of the mine’s latest technological preservation update, ensuring these historic shafts remain safe and accessible for decades to come. When you visit, you’ll don a traditional green-and-brown miner’s jacket and a helmet. The 90-minute guided tour takes you 96 meters underground to the unique 18th-century Holy Trinity Chapel, a spiritual sanctuary where miners prayed for safety before their shifts. Keep an eye out for Perkmandlc, the mischievous mine dwarf who, according to local legend, either helps or hinders the workers!
The White Gold: 150 Years of the Idrija Lace School
While men worked in the dark depths, the women of Idrija created delicate masterpieces in the light. Idrija lace (idrijska čipka) is more than just fabric; it is a complex mathematical art form passed down through generations. The year 2026 is particularly momentous as the Idrija Lace School (Čiparska šola Idrija) celebrates its 150th anniversary of continuous operation since its founding in 1876.
I highly recommend visiting during the 44th Idrija Lace Festival, scheduled for June 19–21, 2026. The town transforms into a living gallery with over 10 innovative exhibitions. You can watch master lacemakers at work, their bobbins clicking in a rhythmic dance that hasn’t changed in centuries. For a deeper dive, head to Gewerkenegg Castle, where the Municipal Museum hosts the most comprehensive collection of lace and mining history in Slovenia.
Culinary Traditions: Tasting Idrijski Žlikrofi
You cannot leave Idrija without trying Idrija žlikrofi. These small, hat-shaped potato dumplings are the first Slovenian product to receive the EU’s “Traditional Specialty Guaranteed” status. Traditionally served with bakalca (a hearty mutton and vegetable sauce), they were the perfect energy-dense meal for hardworking miners. If you visit on August 22, 2026, you can catch the annual Idrija Žlikrofi Festival in Park Mejca, where local chefs compete to give this 19th-century staple a modern 2026 twist.
📍 Key Takeaways:
- Double Anniversary: 2026 marks 150 years of the Lace School and a 5-year technological jubilee for the mine.
- UNESCO Depth: Visit Anthony’s Main Road for a deep dive into the world’s second-largest mercury deposit.
- Culinary Heritage: Don’t miss the authentic Idrija žlikrofi, ideally during the August festival.
Planning to explore the depths of Idrija’s history? The drive through the winding Zala valley can be tricky if you aren’t used to mountain roads. I personally drive my guests in a comfortable, modern vehicle so you can focus on the UNESCO views rather than the hairpin turns.

🌟 Tanya’s Local Tip:
In 2026, if you book a combined ticket for the Mine and Gewerkenegg Castle, ask for the ‘Heritage Passport.’ It often includes a small discount on a portion of žlikrofi at local Gostilna Barbara. Also, the mine stays a constant 13°C (55°F) year-round—even in the peak of July, you’ll want a light sweater!
