A bit of info that i have found out so far (sorry if the pictures arnt that good they were taken on my iphone(the original iphone the very first one as thats all i had on me at the time ))

On the opposite bank of the Thames from Runnymede lies the important archaeological site of Ankerwycke, an area of parkland acquired by the National Trust in 1998 and containing the remains of the 12th-century St Mary's Priory and the Ankerwycke Yew - a magnificent tree believed to be over 2000 years old.

i also have the pictures of the tree but not up loaded yet
