Buried deep inside a working mine in northern Italy’s Dolomites, an extraordinary project is taking shape. Engineers are building Europe’s first digital data centre inside an active mine. The Trentino DataMine will soon operate alongside underground storage depots holding apples, wine, and cheese.
This €50.2 million venture, partly funded by the European Union’s Next Generation fund, combines public and private investment. The University of Trento and several local companies are leading the development. Experts say the project could transform how data centres are built and powered in Europe.
Giuliano Claudio Peritore, president of the Association of Italian Internet Providers, called the project “fascinating”. He said mines are usually humid and unsuitable for technology, but the Dolomites’ rock is dry and stable, making it a rare opportunity.
Located 100 metres below ground, the facility promises high physical and digital security. Its position shields it from earthquakes, bombs, and electromagnetic interference. Constant technological updates will protect the centre’s cybersecurity.
The mine, owned by Tassullo, has long stored local produce thanks to its steady 12°C temperature. The same conditions now support the servers, cutting cooling costs and energy use.
According to Dedagroup’s Chief Technology Officer, Roberto Loro, the data centre will share energy with nearby industries. “Those who need heat can use the heat we produce,” he said.
About 60 workers are completing 50 kilometres of cabling and ventilation systems. The underground servers are expected to go live by December.
