The parish of Aylmerton lies in northern Norfolk not too far from its North Sea coastline and roughly 3 miles southwest of the coastal resort of Cromer. Aylmerton sits about a half mile south of the A148 road which links Cromer across the county to the port of Kings Lynn. There are two distinct parts to Aylmerton, a presence on the A148, with inn and filling station, and a collection of farms and cottages around a three-way junction to its south. Aylmerton sits upon a noticeable ridge, slightly higher ground for Norfolk, which was formed by glacial deposits giving it a much less fertile soil than normal for the county. As a consequence, whilst still rather important, early gazetteers estimate that only 60% of the acreage was set to arable, much less than is typical. A further 20% was set to woodland and this land-use continues today with The Great Wood shared between Aylmerton & neighbouring Felbrigg. The Lion's Mouth is a popular spot for local woodland walking.

St John's church sits between the two parts of the village on the eastern side of Church Road and north of the main group of properties. The presence of a round tower is normally indicative of a very early church in Norfolk but St John's is 13th century rather than earlier, Pevsner, however, hesitates as 20th century rebuilding may indicate his dating details are corrupted by later changes. The remainder of the church is typical for Norfolk with a mixture of both Decorated and Perpendicular styles indicating a build during the wider 14th century. The nave shows a pair of the former style whilst the chancel has rather more whilst south face windows a primarily Perpendicular. The church, however, has received much attention across 19th & early 20th century as already alluded to. Besides the work of 1912 rebuilding the tower's upper stages, further restorations of both 1865 & 1876 are noted all making substantial changes to the church. Church Road is narrow and parking needs careful thought to avoid blocking. The churchyard sits above head height at its northern end buts slopes closer at the south where the main entrance lies. Once inside the churchyard is open & uncluttered with no obvious obstacles for the photographer.
