Idrija can be explored through three distinctive themes: its mercury-mining heritage, bobbin lace and paths through a protected natural landscape. The technical side of its mining history is also tangible: notable sites include an old mine entrance, a large wooden water wheel and a historic smelting plant. Visitors who want to combine culture and nature can also follow an almost level walking path to Wild Lake.
Mining History and Technical Monuments
Anthony’s Main Road is the oldest preserved entrance to a mine in Europe; it was created in 1500. On a guided tour, visitors explore underground tunnels containing cinnabar ore and glittering droplets of mercury. The tour also includes a unique underground chapel. Here, visitors encounter mining not only as industrial history, but also as an underground place with structures of its own.
At the Hg Smelting Plant, the focus is on the technology of mercury production. It is home to the world’s largest rotary furnace for extracting mercury. Experiments, animations, videos and mercury-related equipment explain the metal’s importance and uses. Idrija Kamšt presents another aspect of engineering: it has Europe’s largest wooden water wheel, measuring 13.6 metres in diameter.
Gewerkenegg Castle adds the history of administration and storage to these sites. It was built in the 16th century for defence, mine administration and the storage of mercury. Today, it houses the Idrija City Museum. Together, the mine, smelting plant, water wheel and castle offer different perspectives on the local mining history. UNESCO recognises the mining sites of Almadén and Idrija as a unique joint testimony to mercury mining.
Bobbin Lace and the History of the Town
The Idrija Lace School has operated continuously since it was founded in 1876. Visitors can try bobbin lace-making there and see an exhibition of timeless masterpieces of lace-making. The Idrija Lace Festival is a traditional festival centred on Idrija lace. If the festival is important to your travel plans, check the event dates in advance.
The Church of St Anthony is also one of the town’s historic buildings; it dates from 1678. For culinary discoveries, try Idrija žlikrofi: they carry national and European designations as a “guaranteed traditional speciality”. Mining, crafts, architecture and regional cuisine offer different ways to discover Idrija’s cultural history.
Feldban and Paths to Wild Lake
A walking path now follows part of the former Feldban railway line. Numerous remnants of the old railway can be seen along this section. The Idrija–Godovič Feldban is considered an important site of military history and part of Idrija’s cultural landscape. One specific feature of the route is a 25-metre-long tunnel that the Feldban path leads to.
For an outing in nature, an almost level walking path follows the historic Rake water channel from Idrija to Wild Lake. Check trail conditions before your visit. The lake is protected as a natural monument; since opening to visitors in 1972, it has been operated as Slovenia’s first open-air museum. The Zgornja Idrijca Landscape Park also begins on the edge of Idrija. At the Idrijca River, Lajšt offers opportunities for swimming, relaxing and picnicking. Seasonal offerings may change; check a specific offering in advance if it is essential to your stay.
The highlights are distinct: the mine and smelting plant explore technical and historical themes, the lace school teaches a craft that is still practised, and the path along the Rake channel leads to a protected natural monument. You can choose what to focus on according to whether you want to experience mining heritage, bobbin lace or nature in Idrija.
