All Saints is a Grade I listed medieval village church with some evidence of Saxon and certainly early Norman features. It has an C11 nave, a C15 porch and an C11-C14 full height octagonal tower housing six bells. The C14 north aisle contains a fine Norman doorway, moved from a previous position in the church. The nave and chancel were fully re-thatched with traditional reed during 2019-2020.The nave windows contain some important C15 stained /painted glass, thanks primarily to local fundraising, this glass underwent ful; restoration and conservation in 2015.
The church also contains some medieval pew-end carvings, a C15 font, and a rare C17 wooden bier. Victorian features include a finely carved pulpit by W G Keppel and stained glass windows by C E Kempe and J & J King. All Saints stands in a fascinating heritage landscape as the village of Old Buckenham had an important position in the C12 to C16. There are the remains and ruins of two castles and an Augustinian Priory within the parish boundary.
