A Treasure Trove for the Richest: A Mega-Vault is Being Built in a Cave in the Alps (5 photos)
The Swiss Alps have been a haven for luxury goods for years. But now, near the Brünig Pass, the most secure location in the world is being built—or so its creator claims.
Brünig Mega Safe AG and its CEO, Thomas Gasser, are literally building a treasure cave that will look like a location from a James Bond film, reports NZZ.
"There will be a second checkpoint here. Trucks and cars that our clients use to deliver valuables will be inspected here," Gasser explains, showing journalists his high-security facility, which dwarfs Hollywood fantasies.
The vault will receive its first treasures in 2028. In addition to precious metals, art collections, and classic cars, this specialized infrastructure will serve to protect data, ensure long-term archiving of valuable items, and safeguard confidential information. The businessman also assures that his caves will be free of weapons and drugs. One client, for example, wants a cave to hide his 400,000-bottle wine collection.
"Buyers of safes will decide for themselves what technical measures they want to use to secure the vault's interior," says Gasser, whose company will handle everything else: access control, operation, and maintenance.
Storing valuables in the depths of the Swiss Alps is nothing new. For decades, specialized companies have used the Swiss Alpine Redoubt as a fortress for storing assets. The combination of massive rock formations, political stability, and extreme confidentiality has created a market for it. Several companies offer bank-independent safe deposit boxes and vaults in former military bunkers at the Alpine Redoubt or operate underground data centers there. However, these facilities are not intended for civilian use.
Gasser's company builds cave safes for the wealthiest clients. Rental prices for underground vaults start at CHF 775,000 for a usable area of 75 square meters. 210 square meters are available for just under CHF 1.5 million. Larger spaces are also available. Cargo delivery is also possible by helicopter, as the company has a landing pad on its premises.
Anyone investing this kind of money naturally requires legal protection.
"Our unique selling proposition is that our clients' safe deposit boxes are secured by legally enforceable title," says Gasser. Buyers are not acquiring a risky financial product, but a real right, registered in the land registry, underground in Lungern. The company acquired the rights to build cave vaults 99 years ago, and given the global instability, underground bunkers, both for living and for storing assets, are in high demand.
"We are directly experiencing the impact of global crises. The demand for reliable and comprehensively protected security infrastructure has increased significantly following the recent geopolitical escalation in the Middle East," notes Gasser. For example, it is important to clients that the facility be protected from drones. Therefore, the treasure cave will also have a remote security system to ward off uninvited visitors attempting to approach from the air.
Besides the treasure caves, Gasser also built a 300-meter shooting range, a Cantina Caverna restaurant for 100 diners, and a training center for the International Fire Academy underground. However, not all of his plans were successful. For example, the construction of an underground gold processing plant failed. ![]()
