Welcome To Idrija, A Town Of Mercury, Lace and Zlikrofi

Introducing Idrija, Slovenia

Idrija is a lovely small town with a population of just under 6,000 in western Slovenia that can be reached via notoriously winding roads. Located some 50 kilometres west of Slovenia’s capital Ljubljana, the town lies at the base of a valley, amid green hills and is crossed by the Idrijca river. It has a typical central-European architecture and you can see a strong influence of the Austro-Hungarian empire during the past centuries, especially in the town’s main buildings. Today, Idrija is best known for three things: mercury (commonly known as quicksilver), lace and zlikrofi.

Mercury mines brought Idrija wealth. After mercury was discovered in the area around 1490, people from across Europe flocked to Idrija. The exact details of the discovery have been lost to history, but according to a local legend, a pail maker was washing his products in a nearby stream when he discovered something shiny at the bottom of a pail. The mysterious substance was mercury. Idrija’s mines are the second largest mercury mines in Europe and the reason for Idrija’s spot on UNESCO’s World Heritage list (in 2012 UNESCO granted World Heritage status to Idrija’s mercury mine, together with a similar mine in Almadén, Spain). A first-hand experience of how mining looked in the old days is provided at Anthony’s Shaft, situated on the southern edge of the town. This atmospheric network of tunnels was built in 1500 and is one-and-a-half-kilometre long, 600 meters wide and 400 meters deep. A tour of the shaft starts with a brief introductory movie and then the visitors are led down the shaft itself, where mining techniques of the past are demonstrated.

Idrija is also famous throughout Europe and beyond for its lace, which is on display throughout the town. The first written mentions of lace making in Idrija date back to the 17th century. By that time, the town was becoming famous for the intricate craft practiced by the women of Idrija. The tradition finally led to the creation of a lace making school in 1876 (it is the biggest and oldest lace school in the world). For the first time, the lace-making skills weren’t just passed down from one generation to another, but became officially taught in school. Today, the Idrija Lace School is still active and helps keep the local tradition alive by passing the art of lace making on to the younger generations.

Idrija has a major culinary claim to fame in the zlikrofi, ravioli-like pockets of pasta stuffed with potato, onion, minced lard or smoked bacon, herbs and spices. Freshly made zlikrofi are served in most of the local restaurants. They are accompanied with the typical meat sauce, bakalca, made from mutton or rabbit meat. They are also served as an independent dish with pork cracklings or butter, or as side dish with meat, meat sauces, roasts, sour turnip or sprinkled with crumbled Gorgonzola cheese. The exact origin of zlikrofi remains a mystery, but according to written sources, they were already common in the 19th century. In 2010 zlikrofi were awarded a protected geographical status (the first Slovenian dish to get such recognition).

The award-winning Idrija Municipal Museum, housed in the Gewerkenegg Castle, which dominates the old centre of the town, has some fantastic collections which deal with mercury, lace and local history. The collections are exhibited in three wings centred on a lovely courtyard, and an accompanying booklet guides visitors through the rooms.

Other worth-seeing attractions in Idrija and the surrounding area include the Kamst (a 13.6 meter waterwheel made of wood that was used to pump the water out of flooded mines from 1790 until 1948), Miner’s House, the Municipal Apiary, and the Wild Lake (a small, emerald green lake fed by a deep karst spring).

The Divje Jezero Lake or Wild Lake in Idrijski Log near Idrija in western Slovenia
Divje Jezero or Wild Lake as it is called in English is a very unique and mysterious karstic lake located in Idrijski Log near the town of Idrija. Since 1967, the lake has been protected as a natural monument of national significance of Slovenia. In 1972, the area of the lake was arranged into the first Slovenian outdoor museum in nature. What makes the lake so extraordinary is its Vaucluse spring which has been explored by the most experienced Slovenian divers to a depth of 160 metres (525 feet). There’s something magical about water that just spontaneously flows from the earth. Normally, the lake’s emerald green surface is calm and peaceful, but after a few rainy days the water that gathers from the entire area of the Crni Vrh plateau and the Javornik Hill starts bursting out from the underground.
