Ubbeston is in central E Suffolk, towards the N of the county, 5 miles SW of Halesworth, in the arable boulder-clay plateau typical of High Suffolk. The church and hall site that are all that remain of the village are sited on the rising N bank of a stream that flows eastwards to join the river Blyth at Halesworth. There is a slightly larger settlement at Ubbeston Green, 0.4 miles to the S.
The church consists of a nave with a S porch, chancel with a N vestry and a W tower. The flint nave and chancel are equally tall. The nave is 12thc., with round-headed N and S doorways; the N now blocked and visible only inside, and the S protected by a 15thc. brick porch with a battlemented parapet. Above each of these lateral doorways can be seen traces of large, blocked 12thc. windows. Three 15thc. windows have been inserted in the nave walls, two on the N and one on the S, the western N window having brick tracery. What appears to be a N buttress between the nave windows is in fact a modern chimney. An obscene relief set high on this is probably not medieval. The arch braced roof covers both nave and chancel with no chancel arch. The roof is also 15thc., much renewed. One of the chancel windows, on the S, is of brick and later than the other 15thc. windows. The priest's doorway could be ofc.1300. The modern lean-to vestry is brick. The west tower is 15thc., of brick. The diocese disposed of the church in the 1970s, and it is now a private residence and business premises, not normally accessible to visitors. The author and the CRSBI would like to express their gratitude to the owners for generously allowing access to record the 12thc. sculpture. The only Romanesque sculpture is on the S doorway.
