The church is Grade I listed as a building of outstanding architectural or historic interest.

The Church of St. Peter at Farndon[1] "was erected during the reign of Queen Elizabeth, and... consists of chancel, nave with clerestory, a south aisle with an arcade of three bays, a western square tower containing four bells, and with an entrance porch.

The date on the nave roof, which is well constructed, is 1664, and there are two stained glass windows of some merit, one on the south side of the chancel and the other in the aisle.

The sword is thought to represent "evidence of Danish and Viking attacks in the Newark area,"[2] and the sword is illustrated in David Kaye's "History of Nottinghamshire."

In recent years, the four church bells have been augmented to six and re-hung.
