Fine 12th century arcade separates nave from north aisle, its pointed arches rest on large based pillars, some with ancient graffiti. Bold leaf carvings decorate the capitals. Of particular note is the vast and ancient font, which is possibly Saxon, and the Paschal candle stand made from a piece of oaken roof timber from Lincoln Cathedral. Ancient texts depicting the 10 commandments hang inside door. The capitals are decorated with bold leaf carvings. The chancel was added later, and the glass in the east window dates from 1958. The church has required substantial renovations at various times. In 1845 Archdeacon Stonehouse reported that 'Owmby Church is an old ruinous fabric, held together by the lead covering the roof'. The roof itself did then collapse in 1939, revealing beams and rafters that had been ravaged by woodworm. Repairs were rapidly carried out, and by January 1940 a new roof and been constructed above the nave, aisle and tower. Although only one bell is able to be rung, the three bells all have rather unusual inscriptions on them: Let us remember the 5th of November WSHW 1687 When you die aloud I cry WSHW 1687 God save the King WSHW 1687
