The Forbes family owned the land and constructed Callendar House as their family home, the mausoleum which was built for William Forbes wife now sits isolated in the woods.
A wide perimeter wall and lack of foot traffic make it slightly eerie.
There is also a graveyard for other family members and workers which has seen the ravages of time/vandalism
A large tree has came down just inside the entrance as can be seen in the last photo
