The diverse and unique industrial and technical heritage of Idrija’s 500-year-old mining history was inscribed on UNESCO World Heritage List in 2012. One of the crucial parts of the mercury mine was the smelting plant, which stopped operating in 1995. Its renovation and renewal was a significant challenge in terms of financing and expertise. The energy renovation of the building was carried out in accordance with the possibilities and specifications of the building, which belongs to the technical cultural heritage. Today the building serves as a museum with a visitor center that was additionally extended to the lower part of the smelting plant. In 2020 it won the 2nd prize of the ‘Destination of Sustainable Cultural Tourism’ award under category of industrial heritage. The theme of the 2020 edition of Awards was ‘Special interest tourism development and promotion based on Cultural Heritage’. The Awards contest was open to tourist destinations across Europe, to showcase their results and outputs in sustainable cultural tourism under five selected categories. It is annualy organised by European Cultural Tourism Network.

RENOVIERUNGS-PROZESS

Architektur

BESCHREIBUNG

The project comprised the reconstruction and extension of the existing ore separation facility and construction of a new building intended for reception of visitors and hosting a permanent exhibition 'From ore to mercury drops'. In the following, we will focus only on the building that has been the subject of renovation. The building is built and dimensioned accordingly to its industrial purposes. It is built as a massive concrete frame structure filled with bricks and windows. The extension made on the right side of the existing building is also modeled in the same way as existing structure. There are new connecting stairs between the ground floor, 1st and 2nd floor, which are made of reinforced concrete. There are also external stairs made of the same material, through which evacuation is possible. The stairs connecting the basement and the ground floor are made of steel. The entire building except the basement is additionally thermally insulated on the inside. The roof is made of reinforced concrete beams, to which a wooden substructure is attached. The asbestos roofing has been replaced with a new suitable corrugated roofing. The roof is thermally insulated. The window openings remained the same, and the windows were replaced with ALU windows with double glazing.
Städtebaulicher Kontext
The building is situated within the industrial area of Idrija. Part of the larger area was sold to another company after the mine stopped its operations. This changed significantly the former visual identity of the town.

DENKMALWERT

ERHALTENSWERTE ELEMENTE
The diverse and unique industrial and technical heritage of Idrija’s 500-year-old mining history that tells the story of mercury was inscribed on UNESCO World Heritage List in 2012. Many mining facilities, machines, equipment and documents were preserved during the Idrija Mercury Mine’s closing down and liquidation process. One of the crucial parts of the mine that has not been renovated was the smelting plant, which was in danger of losing its protected properties due to its deteriorating state. The smelting plant of the Idrija Mercury Mine ceased to operate in 1995. The area of the monument covers the cableway end-station, the building of the ore separation and crushing plant, conveyor belts, collection silo, rotary furnace, smoke chamber, smoke pipelines and chimney, and the Špirek-Čermak furnace. The smelting plant represents the final phase of the mine’s development.
Denkmalwert und wie er bestimmt wurde
Idrija was known for centuries as the second largest producer of mercury in the world. The mine has stopped with excavations in 1995 followed by the intention to have the industrial heritage listed on UNESCO list. Till 2012 the mine with industrial buildings and other facilities is inscribed on UNESCO World Heritage List. In February 2014, the public institution Idrija Mercury Heritage Management Centre (CUDHg Idrija), took over the management of the smelting plant area from the Idrija Mercury Mine, Ltd. – in liquidation. They successfully applied to a call for proposals to co-finance the project ‘Idrija – smelting plant area of the Idrija mercury mine – 1st phase of reconstruction' under the EEA Financial Mechanism Programme. The goal of the project was to preserve the endangered cultural monument and enrich it with new content. The Špirek-Čermak furnace was listed already in 1986 as a monument. Together they represent a part of the UNESCO mercury heritage in Idrija.

Erhaltungszustand

Erhaltungszustand der Gebäudehülle
The building was abandoned since 1995 when the mine has stopped operating. After that there was no maintenance.

Ziel der Sanierung

Renovation + Extension
The goal of retrofitting was to preserve the endangered cultural monument and enrich it with new content, enhance its modernity and attractiveness, revive its heritage with educational content, raise awareness of the importance of preserving cultural heritage, and enhance tourism opportunities in the area. The project began on 30 December 2014 and was completed on 31 January 2017. The goals of the 1st phase of the project, which comprises the reconstruction and new construction of the existing ore separation facility, a new reception and exhibition centre for visitors, and the exhibition 'From ore to mercury drops', were: - to preserve and restore the cultural monument of national importance inscribed on UNESCO World Heritage List, - to finally restore and present the machines and devices in the reconstructed ore separation facility with a demonstration of their functioning within the scope of the exhibition 'From Ore to Mercury Drops', etc.
Gab es eine Änderung der Nutzung?
The former industrial plant became a presentation center and a museum to show the visitors part of the mercury mining production process.
Was the intervention planned following a step-by-step approach?
Two investment phases were planned. The first one is finished. The second one will focus on the furnace, extraction and packaging of mercury in cylinders.

SONSTIGES

In some parts of the industrial plant there were additional modules (toilet, seminar room, elevator) established. They are heated and therefore also isolated as separate modules in the building.

In addition to the visitor centre all other parts of the building are kept very close to the initial state to serve the demonstration of the process. Areas where visitors stop (presentation elements, toilets) are separated from the other non heated areas.
