[1] Climbing the stack is not allowed but tourists may view the rock from a distance.
Lange Anna is somewhat similar to the Old Man of Hoy or Old Harry.
The stack is subject to severe weathering wear and decomposition.
It was decided that any further effort for its conservation could do nothing but slow down the process, so the Lange Anna today is consigned to its fate.
Experts assume an acute danger of collapse of the top two thirds because of an unstable layer of sands 16 metres (52 ft) above sea level, which already is the thinnest part of Lange Anna.
