NB:As can clearly be seen in this image,most of the dressed stone has been robbed from the buildings leaving just a rubble core.Badly overgrown and in a perilous state,large sections of the site have been declared" out of bounds",for fear of building collapse.Renovation of the surviving structure,is taking place,but due to lack of funds,the pace of this regeneration is very slow.
