The Island was in full defensive swing in the lead up to and during the 2nd World War as it was seen as being in the forefront of the battle area. It was very likely if a German invasion was imminent for it to be one of the first places they would try and take in order for them to have a secure beach head and thus allowing them to launch their blitzkrieg method of advance easily into the mainland.
With this in mind the War Office devised several defence mechanisms and prepared points of special interest that in the event of an evasion could be used to slow down any advancing forces. One of these methods was the deployment of several pillboxes, carefully positioned throughout the Island.
The site where the Yaverland pillbox stood is now a housing estate so there are no signs of any actual pillbox.
Each pillbox had its own style of construction, and details of which can been had by following the link in the "Resources" tab.
