The Untergunther is a clandestine group with a mission to restore the neglected heritage in Paris. It is a member of the UX, a coalition of groups sharing complementary activities, which include The Mouse House and La Mexicaine De Perforation.
These self-styled "guerilla preservationists" have more than a few notable achievements. For one they built an entire cinema within the catacombs under Chaillot Hill, just a few meters from the Eiffel tower. Unfortunately for them this popular social spot, which had a well stocked bar, was accidentally discovered by police on a training exercise.
The group's most famous exploit would have to be the repair and renovation of the famous Panthéon clock.
