There is nothing at the headline coordinates.
To find the coordinates for the cache you'll need to have completed both the 'Streets of Ottery St Mary' and the 'Coleridge and Ottery St Mary' Adventure Labs.
PLEASE NOTE THAT ONE OF WAYPONTS FOR THE COLERIDGE ADVENTURE LAB IS CURRENTLY INACCESSIBLE DUE TO STORM DAMAGE, SO I'VE TEMPORARILY ADJUSTED THE COORDINATES SLIGHTLY AND CHANGED THE QUESTION ACCORDINGLY.
Streets of Ottery St Mary Adventure contains 5 letters which when put in the correct order form a common British FIRST NAME and Coleridge and Ottery St Mary contains 5 letters which put in the correct order form a fairly common British SURNAME of a person relevant to the town. You'll need to enter this first and surname as one ten-letter word IN CAPITAL LETTERS into the certitude link on this cache page to reveal the coordinates for the final hide, which is a short walk from one or more of the stages.
You can validate your puzzle solution with certitude.
