The parish of Dilham lies in northeastern Norfolk about 4 miles southeast of the market town of North Walsham. Dilham sits just to the east of the A149 road which connects Cromer with Great Yarmouth, just by where this road crosses a tributary of the River Ant, one of Broadland's main rivers. The parish sits on the border of prime agricultural land and the grazing marshes and water meadows on the Ant valley. The main street of the village wanders northwards from the main road and most of the village's housing can be found here. The land is quite low lying being less than 10 metres above sea level but the Hall and church sit on a relative rise and keep their feet dry.

St Nicholas' church sits in splendid isolation about 3/4 miles northwest of the main part of the village and adjacent to a lane in farmland. The first thing you notice is the lack of a tower which gives the building a strange look, the tower was round but not a Saxon work being in the Perpendicular style, the remainder was built in 1835. The rest of the building, too, is largely Perpendicular work typical of a Norfolk church. The site is a rather enclosed one being surrounded by a border of trees, a rarity in this landscape as large arable fields predominate.
