Selattyn is a village in the NW of the county, a mile from the Welsh border and 3 miles N of Oswestry, The church is in the centre of the village and consists of a 13thc nave and chancel, 18thc tower, 19thc N aisle, N and S transepts. There is a font at W end of the nave close to S doorway. It probably dates from the 12thc or early 13thc.

The settlement itself is not mentioned in Domesday Book, but it may have been part of the nearby (although very small) Weston Rhyn, which was held in the Confessor's time by Siward the Fat and in 1086 by Reginald the sheriff. According to the church guide (see bibliography), the church is first mentioned in Papal taxation records in 1292.

While the church guide dates the font to the 13thc, the form and details of decoration could be safely dated to 12thc. The leaf motif is similar to some of the leaves on the capitals in the nave at Morville, but the motif there is more three-dimensional.
