The parish of Ashwicken, it was united with Leziate in the late 15th century, lies in western Norfolk roughly 5 miles east of the port of \King's Lynn. Ashwicken sits on and south of the B1145 road which runs west to east from King's Lynn across to Bawdeswell. The road follows a strip of slightly higher land and this emergence above low-lying and marshy ground is where the settlement arose. The soils here, however, are poor and underlain with the narrow outcrop of Carrstone, an iron-rich but nutrient poor sandstone. The farming here was a mixture of arable and pastoral with some land managed for woodland but with other areas set to heathland. The sands and gravels deposited by retreating glaciers have, however, been attractive for road-building and numerous pits, particularly at Bawsey have been opened to extract these materials. Ashwicken was a relatively modest parish with few parishioners, the location of the church close to the hall is perhaps indicative of an estate parish with most land held by a single landholder, this tends to prevent a distinct village growing up.

All Saints' church sits by that hall accessed along a sandy track bordered by impressive chestnut trees and west of Church Lane. The church has its origins in the late 13th century, a period when Early English Gothic was Transitional into the Decorated era. Only the western tower remains from this early time and it has been much modified over the centuries, repairs in the 18th century reduced its bell-stage in height and in the 19th century the pyramidal roof was added. The nave shows the later style of 15th century Perpendicular and is perhaps indicative of a general rebuild during that great church-building era. It is documented in 1777 that the church was unfit for use through lack of repair but the Victorians got to work as they almost invariably did. During the 1860 restoration which added that roof to the tower, the chancel was completely rebuilt, the nave saw most windows renewed and the southern porch also rebuilt. The churchyard sits at the end of the sandy track with space for cars to discretely park, the hedged churchyard has few obstacles for the photographer.
