News regarding this site (Sprockhoff 808):
Modern people made it collapse ... hooray. Most probably due to continued climbing on top of the chamber a central long-side orthostat collapsed end of December 2013. This caused capstone C2 to fall. The previous precarious state is visible in some recent of the photos here. It still looked ok 14 years ago.
Access to ALL the sites has been blocked. Thanks to the groups of well-off vandals climbing on top of the chambers....
Several reports in Newspapers. This is from a small local paper:
