First stop on my sightseeing tour was the Gwerkenegg Castle. Though it looks like some feudal lord lived in here, this Renaissance building was made to be the administrative headquarters of the mine. It now houses the excellent town museum. Entrance costs 3.5 EUR, and includes a booklet in English detailing all rooms. In one of the first a bowl full of mercury is shown, with an iron ball floating in it (mercury is 2 times heavier than iron). Interesting stuff. Other rooms include one full of black-ad white photos of daily life in Idrija in the early 20th century. We see girls lace-making at school, that other craft where Idrija is famous for. The women in town started doing this to earn some additional money to their husband’s miners wages.
Unfortunately no other mine-related sites are open to the general public, you’ll have to arrange for a tour somewhere to visit for example the pretty miners house above town (see 3rd small picture). It looks quite big, but several families lived in it. The town center is worth a stroll for seeing the opulent Town Hall (1898) and little Mine’s Theatre (1769). For lunch I had the local žlikrofi with Gorgonzala sauce on top, very filling.
I then had to kill some time before the 3 p.m. tour at the Anthony’s Shaft would start. I had seen about all there is to see in this small town, so I just enjoyed the sun and a cappucino on a terrace. In the end I was glad that I had waited for the tour to start, as this is where the mercury mining history comes alive. In all it takes about 1 hour and 45 minutes, of which you spent over an hour underground. I found the guide very good, explaining each element clearly in both Slovenian and English over and over again. I was in a group of 10 tourists, from all over the world including a couple from Iceland.
Of course during my WHS travels I have been to many mines before: gold, silver, copper, coal – the list is full of it. I wondered how mining of mercury would be different. Well, it’s pretty similar. They hack and blow away the rocks to get at the precious metal, run little carts on rails to transport the material and build an elaborate underground system. What I didn’t know is that mercury not always comes in the form of little silver coloured balls: 70% of the mercury of Idrija derived from a red stone, which had to be worked and heated afterwards to get to the liquid metal. You can see both forms during the tour, the materials are still present in the mine walls. The mine wasn’t closed because there was no mercury anymore, but the prices had sunken so much that it wasn’t profitable anymore.
I visited Idrija, Slovenia in April 2014. I wasn't expecting much as I'm not so keen on industrial WHS. However, I was pleasantly surprised with Idrija. It is quite remote and you won't visit by chance, that's for sure. It's a nice drive through winding roads and it has much to offer even though it appears to be a ghost town now. The industrial landscape is immediately visible with metallic structures, smelting plants, mines and several shafts. I visited Anthony's shaft in time for the 10am tour in English (the other guaranteed tour is at 3pm). The tour in "the second largest mining site in the world" takes around 2 hours including a 20 minute informative video. You get to wear a protective waterproof miner suit and a hard hat before entering the mercury mine. The guide makes the trip interesting and describes the miners' everyday life as well as the different developments over time. The highlight of my trip was actually seeing naturally occuring mercury droplets in the mine as well as getting to appreciate the different structures (wooden and iron) used to support the shaft. For those who are more adventurous, group tours can be organised to go even deeper inside the shaft with torches instead of electricity lighting and going down ladders apart from the 500 stairs you go down in the traditional tour, eventually getting out in the nearby village. The traditional loop was more than enough for me to grasp the size and importance of this industrial site. I would vividly recommend using the hard hat if you're taller than 6 feet ... you'll definitely won't regret it! Apart from the mine, there's a worthwhile hike through the greenery to see the Kanomilja or Ovcjak Water Barrier, the Vojsko-Idrijca Water Barrier, the Putrih's Water Barrier and the Belca Water Barrier. If you have enough time go for it, otherwise I'd highly recommend visiting the shaft and the old town itself, with its church, municipal museum, castle, old cinema, etc. It might be quite difficult to find an open restaurant in the slow months but do try the local speciality "zlikrofi". All in all, I enjoyed my visit even though it isn't one of the most outstanding WHS in the list.

I enjoyed the visit to the mercury mines of Almaden like a child.
I paid the entry fee (13 euro) and joined a small group of tourists. We were given helmets to protect our heads, just in case, and followed the guide. We all were Spaniards, so the explanation was in Spanish language, although the guides could also speak French and English.
We took the lift and descended 50 meters. There were more floors, until over 700 meters depth.
During two hours we walked along corridors and tunnels with stops for explanation in front of the old machines used to extract the cinnabar, the ore of mercury, or quicksilver.
The quicksilver from Almaden helped to extract the silver in the Spanish colonies in America during the colonial times.
After the mines we boarded a train, then a minibus. We saw museums and games for children. All was very didactic, very attractive, even for adult people.
Apart from those mines, Almaden has a hexagonal arena and a hospital unique in the world, where the workers of the Almaden mines were hospitalized when they became sick for mercury poisoning. In some periods of time, in the past in the Almaden mines was used slave labor.

After catching the 08.15 bus from Ljubljana station to Idrija, I reached the Antony Mine in time to get kitted up for the 10.00 tour of the mine shafts.
The tour descended only 3 of the 15 levels, but the atmosphere was stifling all the same. Down in the tunnels there were several displays showing methods of mercury extraction over the centuries. There was also a rock face with drops of mercury oozing out of it.
Like Ian I also enjoyed a plate of Idrija zlikrofi (mushroom ravioli) after the tour.

I visited Idrija, the Slovenian part of the WHS, in May 2012, expecting that it would be inscribed a few weeks later. Idrija is a small town with about 6000 inhabitants, 50 km from Ljubljana on the junction of the subalpine and the karst areas. The town lies in a picturesque valley surrounded by forest, quite unusual for a mining town. Mercury was mined for 500 years and until its closure Idrija was the second largest mercury mine, Almadén being the first. The WHS consists of seven parts: the old town, two other sites in the vicinity of the town centre, and four water barriers located in the surrounding mountains.
The historic mine, the Anthony's Shaft dating from 1500, is situated in the old town and is open to visitors. The guided tour takes 1.5 hours, it starts with a 20 minute multivision presentation. The oldest mine galleries are narrow and you have to bend down several times, the newer mine tunnels are wider and higher. The different steps of mercury mining and the techniques and tools that were used over the centuries are explained. And you can also see the underground chapel dating from the 18th Century. It was interesting to learn about the specifics of mercury mining. The mercury ore deposit is relatively small: 1500 m long, 600 m wide and 400 m deep, just below the town. In Idrija the metal was found both in its elemental liquid form and as cinnabar ore (mercury sulfide). However, the tour was very similar to other mining sites, nothing extraordinary.
In the old town are several buildings that are associated with mining: the entrance building to the Francis' Shaft (now a technology museum with pumps, engines and other devices), nearby a historic miner's house, the Castle Gewerkenegg (formerly the administration of the mining company, now the Municipal museum), a miner's theatre, a school building. The second part, about one km from the city centre, is the smelting plant, which needs to be reconstructed. It can only be visited from the outside.
The third part is located at the outskirts of Idrija close to the historic entrance of the Joseph's Shaft and comprises of a large water wheel (Kamšt) from 1790 and a water channel (Rake). But beware: the pump house is not regularly open, you have to ask for a guided tour at the museum. Unfortunately, we missed that. A trail leads alongside the Rake water channel through a nice forest with beeches and firs and ends after 3 km at the Kobila dam and the Wild Lake (Divje jezero). The dam and the Rake channel were used to regulate the water flow for the drive of water wheels and the transport of tree trunks that were used for supporting the mine tunnels.
The final parts of the site are four water barriers (klavže) on the Idrijca and Belca river. If you continue on the hiking trail at the Wild Lake, you would reach two of the water barriers after about 12 km. But this was a bit too far, so we decided to return and tried to go as far as possible by car. First, we drove on an asphalt road to Idrija Bela, a small village with a few houses, where you can bathe in the river. Then, after one kilometre the road became bumpy and narrow. We parked our car and went further by foot. After about 5 kilometres (moderatly uphill along the Belca) we reached the first water barrier, the Brusove klavže (photo), and after another kilometre the Putrihove klavže. These klavže are massive locks built of stone, which at a first glance appear a bit oversized for the small river. They were used to dam water and when enough water had accumulated, the locks were opened to allow the water to transport the wood downhill. The klavže are accessible, you can walk on the stone walls and go downstairs to the watercourse. I enjoyed our short hike through the beautiful forest scenery and the klavže are really impressive.
There is a lot to entertain visitors for a whole day, and Idrija offers enough for every taste: a mine, historical technical equipement, a pleasant town, a rewarding museum, and in fine weather the nice landscape contributes much to the pleasure of the visit.

“…and if I hire a car I could make it to the disused mercury mine!” little did I know that this ‘obscure’ holiday destination that I was trumpeting in the pub would prove to be such a rewarding target.
I drove to this site fresh from landing at Trieste airport, initially just assuming I would be getting in a pre-emptive tick on a site that was soon to be inscribed on the World Heritage list and little else. It actually turned out to be an exceptionally rewarding way to start my holiday in this great little corner of Europe.
Idrija is situated in a wonderfully verdant valley and the road through it was a pleasure to drive. When I arrived at the town I was suitably impressed. Rather than being the slightly utilitarian mining landscape I was expecting it was actually a rather pretty Central European renaissance town. There were lovely winding streets, trickling streams, a little white church nestled above the town and an imposing arcaded castle housing the wonderful town museum.
I arrived just too late for a tour of the mine shafts, so headed for the museum which was exceptionally well presented, and the staff were superb. They gave me an introduction to the life of the town, its heritage and its highlights. There were displays on mercury (including a bowl full of it with an iron canon ball floating atop it), mining, technology, local art, WWI, socialism and lace. Actually the Lace display proved to be very interesting, as it rounded out the life of the town, whilst the men were down the mines the women were making lace. It also prepared me for the Lace festival which had taken over the main squares and provided a great ambiance.
After soaking up the atmosphere and enjoying a plate of local speciality žlikrofi, I drove of north through the even more beautiful Soča valley seeing the Julian alps rise around the astounding emerald blue waters.
It looks likely that Idrija will be added to the World Heritage list in 2012 alongside Almadén in Spain. I’m not really sure how much of a link there is between these two towns aside from the large mercury mines, however if Almadén is half as rewarding as Idrija, then I would thoroughly recommend a visit.
