"Officers admit they are at a loss to know who built or used one of Paris's most intriguing recent discoveries."

This is the story of an underground cinema recently discovered in part of the enormous tunnel—cave network under Paris.

Since the web article is likely to disappear (or effectively disappear behind access control)¹ here are some of the highlights which intrigued me:

Police in Paris have discovered a fully equipped cinema-cum-restaurant in a large and previously uncharted cavern underneath the capital's chic 16th arrondissement.
Officers admit they are at a loss to know who built or used one of Paris's most intriguing recent discoveries.

"We have no idea whatsoever," a police spokesman said.

"There were two swastikas painted on the ceiling, but also celtic crosses and several stars of David, so we don't think it's extremists. Some sect or secret society, maybe. There are any number of possibilities."


The police were on a training exercise and came across the carefully-guarded entrance to the cinema. The projection and bar equipment, along with the functioning electricity supply, phone lines and cous-cous steamer², would suggest that the site was far from abandoned.

Three days later, when the police returned accompanied by experts from the French electricity board to see where the power was coming from, the phone and electricity lines had been cut and a note was lying in the middle of the floor: "Do not," it said, "try to find us."

...

Patrick Alk, a photographer who has published a book on the urban underground exploration movement and claims to be close to the group, told RTL radio the cavern's discovery was "a shame, but not the end of the world". There were "a dozen more where that one came from," he said.

"You guys have no idea what's down there."

Ooooh.

¹ You know, there are whole companies making a living out of that sort of malarkey -- making money out of crosswords and archival newspaper content. I ask you ...
² All French cinemas are required to make cous-cous preparation facilities available to all customers.
