Here is a little sketch of the site to give you an idea of the layout . It is not accurate , just my interpretation of where things are located .
Judging by the amount of foliage around the site , this image was taken before remedial works to the site began in earnest . It is far less overgrown now .

Also not to be forgotten is llanyrafon Mill , located just across the road from the Manor
