The parish of Guestwick lies in the northeastern portion of central Norfolk. Guestwick lies in a large area of Norfolk devoid of any significant numbered roads, it sits about 3 miles northwest of the large village of Reepham and about 7 miles southeast of the market town of Fakenham. Guestwick is a relatively small place with no distinct village as such merely a scatter of farms and cottages cross the landscape. The landscape is largely flat or at best gently rolling and dominated by arable farming. Guestwick and the surrounding area were local hotbeds for nonconformism and there were several sects operating in the area so if the entry you seek is missing from here then one should check those appropriate other congregations when completed.

St Peter's church is sited at the notional centre of Guestwick on the eastern side of Wood Dalling Road, the main north/south running lane through the parish. The church has two distinct histories, Pevsner speculates that an early Norman church once stood and was almost completely rebuilt in the early 15th century. His speculation has the tower at the crossing of a small Norman church, it is now a northern tower of the expanded and enlarged building. The dates for the early church are given as late 11th century and are evidenced by excavations carried out in 1983 when the original floor plan was discovered. The current church is almost typically Norfolk in being Perpendicular apart from re-roofing and modification to some windows in the 19th century. The church sits in a slightly elevated site with its western end close to Wood Dalling Road, a gravel path grants access from a metal gate at the southern end of the site. The best views are perhaps from the road, itself.
