The cache is called "All That's Left" because it is placed on all that is left of the previous building to occupy this site. These white railings are part of a bigger stretch of railings that used to surround a school playground (but when I remember them, they were green).
The school was built on land that was donated by the Rodgett family of Sandford House. The keystone above the main door bore the date 1885 and this stone now serves as the base for the water pump that is located near South Bridge; there is a cache there too!
There was a large playground at the front of the school and a field at the back where you could play inthe summer and where the sports' days were held. When I first went there, in 1973, the school was called Wareham Infant School, but the name was changed in the mid 1970s to Rodgett County First School. The school closed in 1982 and was demolished a few years later. The current buildings were then erected on the site.
This area can be very busy with lots of muggles, so please seek the cache at a quiet time and use extreme stealth.
