Radclive is a tiny village in the NW of the county, in the Domesday hundred of Ixhill, less than a mile E of Buckingham. It lies in rolling, wooded pasture, in a loop of the Great Ouse, and consists of a few dwellings on minor roads clustered around the church and the manor house. Radclive Manor is an imposing 16thc timber-framed building with brick infill, that was encased in stone in the 17thc. It stands immediately to the S of the church. Radclive Hall, a smaller 19thc house on the N side of the church, was formerly the rectory.
The church has a nave, chancel and W tower. The nave has a late-12thc S doorway under a timber-framed porch that has been heavily restored, the chancel arch is also 12thc in origin, and the tall, narrow proportions of the nave must be 12thc or earlier. Both the nave and the tower were rebuilt in the 14thc, and at that time the S doorway and chancel arch were remodelled. The nave windows are a mixture of 14thc and 15thc types, while the tower has a reticulated W window and plain 14thc bell-openings and W doorway. It also has diagonal W buttresses, a SW stair and a battlemented parapet. The masonry of the tower and nave is of roughly course stone rubble, whereas that of the chancel is of larger, more regular, blocks of ashlar. The earliest chancel windows are 13thc. There was a restoration by J. O. Scott in 1902. Romanesque sculpture is found on the S doorway, the chancel arch, stones from that arch reset above it in the E wall of the nave, a relief set above the interior W doorway of the tower and the plain font.
