 Chew Stoke is the site of a Romano @-@ Celtic double @-@ octagonal temple , possibly dedicated to the god Mercury . The temple , on Pagans Hill , was excavated by Philip Rahtz between 1949 and 1951 . It consisted of an inner wall , which formed the sanctuary , surrounded by an outer wall forming an ambulatory , or covered walkway 56 @.@ 5 feet ( 17 @.@ 2 m ) across . It was first built in the late 3rd century but was twice rebuilt , finally collapsing in the 5th century . The positioning of the temple on what is now known as Pagans Hill may seem apt , but there is no evidence for any link between the existence of the temple and the naming of the road .
