It is thought that erosion from the sea played a significant part in the early history of Frinton, several of the buildings of the old town being lost to the sea in the Eighteenth Century. The settlement of Frinton dates back to Saxon times, the name meaning “safe enclosure” and there are mentions of William the Conquerer visiting the site in 1086. It is thought that a small settlement of approximately thirty people lived here for several centuries.The oldest building in the parish still surviving, and the smallest church in Essex, is the Old Church of St. Mary at the end of Connaught Avenue overlooking the sea, this dates back in its current form to 1200-1300 AD. Parts of the Nave are of Norman origin.

It's now an offset multi. From the posted co-ordinates, add 9 to the northings and 43 to the eastings. This will give you the final coordinates. The cache is a magnetic micro.
If anybody would like to expand to this series please do, I would just ask that you could let Sadexploration know first so he can keep track of the Church numbers and names to avoid duplication. There is also a Church Micro Stats page found via the Bookmark list.
