Church Of St Mary

The Church of St Mary is a Grade II* listed building located on Main Street in Turweston. It features rubble stone construction, with a lead roof over the nave and slate roofs with coped gables on the other sections. The church was restored in 1863, which included the addition of a rain-water head. The west tower has a saddle-back roof designed by G.E. Street.

Inside, the church has two bays. The north arcade is of Norman style, featuring carved caps on the shafts of the piers, while the south arcade is Transitional, with moulded caps and a pointed west arch. There is a small Norman window on the west wall of the north aisle. The aisles and clerestory contain 19th-century or restored Decorated style two-light windows. The nave roof, dating from the early 16th century, includes moulded tie beams, decorative bosses, and traceried spandrels on the braces. The chancel arch is from the 13th century, and the east window is in the Perpendicular style. The north wall has an arch leading to the vestry and a Decorated crocketted recess that has been filled in. The south wall features an Early English piscina and two arches leading into a 19th-century chapel.

The furnishings are primarily from the 19th century, including a carved stone altar and reredos flanked by figures of saints in niches. The pulpit and low chancel screen are in the Norman Revival style, and there is 19th-century stained glass throughout. Notable monuments include three brasses in the chancel, one commemorating Thomas Grene and his wife from 1490, and a monument on the east wall of the north aisle dedicated to Simon Heynes and his wife from 1628, which depicts two small figures kneeling at a lectern with a baby below, framed by Corinthian columns, an entablature with flaming ball finials, and a lower frieze with an inscription.
