The parish of Fincham lies in western Norfolk roughly midway between the market town of Swaffham and that of Downham Market. Fincham is a large village sitting astride the A1122 road which links those two market towns. The route of this road follows that of an ancient Roman Road and is remarkably straight to prove it to the east of the village. Fincham was sufficiently large in mediaeval times to be divided into two parishes St Martin & St Michael, the latter was demolished in 1745 and the two united. Despite the apparent decline from being large enough to warrant two parishes and to holding twice annual horse fairs, Fincham remains a large and thriving village with all services intact. The nearby air base of RAF Marham has undoubtedly helped in keeping the village thriving. Most of Fincham's properties lie along either side of the A1122 which forms the main village street.

St Martin's church sits towards the eastern end of the village on the northern side of the main road and forming an undoubted landmark for travelers even today. The church is very large as befits a substantial village with the basic design of western tower, nave & chancel augmented by aisles and arcades. The south face which graces the street is particularly powerful statement of the wealth at the date of construction. The church is essentially a Perpendicular build which Pevsner places, through documentary sources, as being completed between the mid 15th century and the early 16th. There was a significant restoration of 1847 and a further remodeling in 1870 to bring about the present building. The church is admirably presented to the street, set back a little and separated by a low carrstone wall. The views from other angles are restricted by surrounding trees.
