DeltaY: Unfortunately this cache must be archived, for two reasons.
1/ Persons unknown have twice stolen the contents of the cache, including one time removing both the cache container and its contents.
2/ Visiting Geocachers do not use common sense and still (not reading the cache page) are removing masonry components from the stone foundation. This practice has led to the Curator of the Mill requesting that the cache be removed.
It is unfortunate that Geocachers and others do not respect property when they the hunt for a cache !!
