Blue Town is a suburb of the town of Sheerness on the Isle of Sheppey in Kent. It sits on the A249 Brielle Way which runs from Queenborough to Sheerness. It sits just outside the dockyard wall which marks the boundary of Sheerness proper and today is largely industrial in nature.
The Church of St Thomas the Apostle in Harty on the Isle of Sheppey in the county of Kent is a Grade II* listed building. The date of founding cannot be fixed with certainty. The official listing dates it to late 11th or early 12th century. In their guide book to the church, Patience & Perks start by reporting the raid by Harold in 1052 and then note that ""The date ascribed to the church of 1089 would be consistent with a re-building following damage by the Danes". However, on the next page they discuss the narrow walls which are indicative of Saxon builders and note that in 1989, when a shallow trench was excavated in the south wall, traces of Saxon work were found. Tufa stone was rarely used after the early Norman period, and so the use of it in a window in the north wall would indicate a date of no later than the end of the 11th century. Patience & Perks observe that the "date of AD 1089 is ascribed to the Norman work, which may well have been the re-building of an earlier structure desecrated by the Danish invaders".
