In the quiet countryside of southern Germany, Christoph Rossner is transforming a former nuclear bunker into what could be Europe’s largest medical marijuana grow-operation.

The 47-year-old entrepreneur says that because of Germany’s tight restrictions on growing, he looked for a site that would offer ample security. “This place is perfect for us,” Rossner said.

In the US, fortified shelters built to withstand catastrophic events from viral epidemic to nuclear war seem to be experiencing a wave of interest in general. Architects are turning abandoned 20th century bunkers into farms, nightclubs, and apartments, while some developers are building luxury underground shelters where the 1% can live out doomsday.

But Rossner has something else in mind for the Memmingen military base, where from 1956 to 2003, the North Atlantic Treaty Organization (NATO) planned to launch nuclear weapons if the Cold War ever escalated. The bunker, empty since 2003, was never used for such purposes.

Rossner wants to retrofit the roughly 11,000-square-foot facility into a cannabis farm, where plants will grow to supply Germany’s medical marijuana market. The facility will also provide cannabis for researchers from the Technical University of Munich and the University of British Columbia in Vancouver.

In vaults the size of shipping containers, chemists will cut highly potent strains of marijuana to create genetic clones, which will be planted to produce more grows. The process ensures consistency from one harvest to the next. Also in the crypt, an industrial furnace once used to incinerate toxic materials will be used to burn any surplus pot — a requirement from the state.

The renovation is expected to cost between $1.8 million and $2.5 million.
