This fourteenth century tower is all that remains of St Michael's Church that was the chapel of Ease for West Milton in the Parish of Powerstock.

In the 1870s the nave was demolished and the stone used to build Powerstock School. The ancient door and windows can still be seen as part of the school. The font was taken to the new church of St Mary Magdalene at North Porton

Hutchins, writing before the demolition, describes this little church as: "...a small building consisting of chancel, nave and western tower, erected in the later Perpendicular period. The arch into the chapel is small and on each side of it is an aperture with foliated head accompanied on the north by two small corbel brackets. The font appears to be Norman and there is a circular-headed Norman doorway on the north side of the nave..."
