"The architectural history of the church has never been properly explained, the north aisle wall especially is a puzzle. The blocked north door is late Norman. West tower post-medieval Gothic of 1712-1713." (Ryder 1982, 89). In a more detailed architectural description Pevsner and Ratcliffe (1967 ,98) note that "The N arcade goes with the early doorway" featuring rounded piers with double chamfered arches. The presence of these elements of c.1200AD supports the early 12th century dates generally assumed for the planning of Bawtry. Unknown legibility of earlier features.
