The church of ST. MICHAEL consists of a chancel 20½ ft. by 15½ ft. and a nave 37 ft. by 20 ft. These measurements are internal. The chancel was rebuilt a few years ago, and the nave, which dates from the 14th century, is now undergoing a complete restoration. It appears to have replaced an earlier structure, probably of the 12th century, as a few worked stones of that date were re-used in the 14th-century walling. Lying in the churchyard is a knee-stone of a gable, once painted and carved with a small couchant lion.
The east window of the chancel is of three lights under a pointed head, without tracery, and the two windows on the south are single lights. The north wall is plastered externally and is without openings. The chancel arch is modern, of two chamfered orders.
The nave has a single 14th-century window in each side wall of two lights with a quatrefoil above. To the east of each is a small hole through the wall about 7 in. square and about 3 ft. above the ground. The purpose of these openings is doubtful. A piscina in the south wall appears to be original and has a trefoiled head. The 14th-century north doorway has been lately reopened; it is of a single chamfered order with a pointed arch. The south doorway is similar and the jambs of both have deep holes for the reception of wooden draw-bars. The south wall has recently been rebuilt, owing to its serious inclination outwards, but the old materials have been carefully re-used. In the side walls several worked stones, including jambs and shafts, of an earlier building have been found in the 14th-century work. The two-light west window is modern. The church was ceiled throughout, but the plaster of the nave roof has been stripped and the old timbers exposed. A small modern turret capped by a pyramidal roof rises above the west end and contains two bells, one dated 1711 and the other undated but probably somewhat older.
The stone font is octagonal and appears to be of 15th-century date. The altar rails are of the early 18th-century baluster type.
There are several monuments in the chancel, the oldest to Thomas Barker, died 1688.
A small piece of ancient glass in the east window bears a shield of the arms of Wisham.
A gravestone in the churchyard commemorates George Apedaile, a Roman Catholic priest who died in 1799, and some English nuns of the order of Poor Clares, who, when banished from Dunkerque by the fury of the French Revolution about 1792, found, by the kindness of Mr. Berkeley, a refuge at Churchill, and William Southworth, their chaplain, who died in 1814. They lived at Wood Farm in this parish.
The communion plate includes an Elizabethan cup with the date 1571 inscribed on it and the date letter for the same year and an exact copy of the same cup inscribed 1905. There are also a pewter flagon and two small pewter almsdishes.
The registers before 1812 are as follows: (i) baptisms 1565 to 1794, burials 1566 to 1792 and marriages 1564 to 1750; after this the baptisms and burials before 1813 are missing; (ii) marriages 1761 to 1812.
