Winterbourne Bassett is a civil parish 6 miles SW of Swindon. The church lies in the centre of the village and was largely built in the 14thc. As Despenser was the Lord of the Manor it is no surprise that this architecture is of higher quality than the usual parish church. The building consists of a chancel, N aisle, and nave rebuilt in the 14thc, a W tower rebuilt in the 15thc, and a S porch built in 1611. The only Romanesque carving in the church is the font.

Winterbourne was granted by King Edgar to Edric between 967 and 975. Winterbourne was also a possession of Amesbury Abbey. Domesday Book records that in 1066 it was held by two unidentified thegns; in 1086 its lordship passed to Humphrey de l'Isle and it was worth £10. Around 1121 his son-in-law Reynold de Dunstanville granted the manor and the church to the Priory of St. Pancras at Lewes. Alan Basset, a member of the Dunstanville family, held the manor from 1194, and the suffix Bassett has been used since then. Hugh le Despenser received the manor in 1281.

The church was restored in 1857-8 by Field and Hinton.
