Situated on the western edge of the village, St. Andrew’s is a very unusual parish church for Rutland as it has a central tower from which extend the nave and the chancel; there is no transept. The lower walls of the central tower, up to the bell-chamber, are of the 12th c. church but there is no sculptural component; the early 13^th c. saw the addition of the upper part of the tower and the broach spire. In the 14^th c., most of the church – the N aisle, nave and chancel – was rebuilt and this included the lengthening of the nave by one bay to the W. Another major restoration was undertaken in 1862-64 and the S porch was rebuilt in 1880. The first two bays of the N arcade of the nave were added in the late 12^th c.

Domesday Book records in 1086 that Glaston was divided in ownership by King William and Countess Judith. The king’s ownership was based on his holding the manor of Barrowden and it six outliers, one of which was Glaston. There is no mention of a church here, but among the listing of the freemen, villagers and smallholders in these outliers, a priest is noted. The first record of the church in Glaston seems to be around the middle of the 12^th c. when King Henry II confirmed the advowson of the church to the Priory of Launde in Leicestershire. The priory maintained the advowson until the 15^th c. when it passed to the manor of Glaston.

The base of the W respond with its upper polygonal mouldings out of line its lower level looks to be a later insertion done as part of one of the major restorations. The overall polygonal aspect of the arcade suggests it is of the Transitional period, around 1200.
