All Saints' Church, Earls Barton is a noted Anglo-Saxon Church of England parish church in Earls Barton, Northamptonshire. It is estimated that the building dates from the later tenth century, shortly after Danish raids on England.The towerThe tower at Earls Barton was probably originally a tower nave, the ground floor serving as the main body of the church with a small chancel annexed to it to the east, as at St Peter's Church, Barton-upon-Humber, built at roughly the same period. A doorway on the south side of the tower, and originally another opening on the west face, allowed access to the outside. The upper floors possibly provided accommodation for the priest or acted as a safe-haven to house treasures, although it has been pointed out that such towers would have been deathtraps in a Viking raid, with their combustible wooden floors and multiple doors. There is a belfry at the uppermost storey.The tower is constructed of stone rubble and rendered on the outside, and is decorated with vertical limestone pilaster strips and strapwork. At the corners of the tower, the walls are strengthened by long vertical quoin stones bedded on horizontal slabs, and hence is termed long and short work. The way in which the tower is decorated is unique to Anglo-Saxon architecture, and the decorated Anglo-Saxon tower itself is a phenomenon that occurs locally, including Barnack near Peterborough and Stowe Nine Churches in Northamptonshire.
