The twin parishes of Weasenham (St Peter & All Saints) lie in northern central Norfolk, St Peter being the more northerly of the two by just a half mile. The village sits on the A1065 road about 7 miles southwest of the market town of Fakenham, that road joining Fakenham with Swaffham. Most of Weasenham St Peter is built wither alongside the A1065 or along the broad lane which heads westwards towards Great Massingham. The area stands around 70 metres above sea level and is largely flat and almost totally arable, although to the north the estate of Raynham Hall adds a little parkland to the landscape. Its main road setting at least has enabled Weasenham St Peter to retain its public house & school although most other village facilities are lost.

St Peter's church stands tight to the busy road in a slightly elevated position with its western tower looming over the road its is a prominent landmark on that route. The church has origins early for a Norfolk church, that western tower is largely in the Early English style of the early 13th century whilst many of the windows on the southern side show the Decorated style. However, that said, much else is typically Norfolk Perpendicular and, given the proximity of All Saints, St Peter is a rather large church with its four-bay southern arcade. The most recent areas are chancel and vestry which were repaired and added respectively in 1870 during the normal Victorian makeover.
