The area makes up the western part of the ecclesiastical parish of Exhall St Giles (which extends from Black Bank in Bedworth to the north of Holbrooks in Coventry).

[1] The parish church of St Giles is on the northeastern edge of Ash Green, in Church Lane, near the junction with St Giles Road (which was known as Dead Lane in pre-Victorian times, as it was the route taken by funeral cortèges).

Indeed, the Coventry city boundary lies immediately south of Ash Green along the former colliery railway line (adjacent to Winding House Lane and Central Boulevard), and the settlement of Ash Green is essentially contiguous with the Holbrooks district of Coventry.

Of particular note in Ash Green is the parish church, parts of which date back to the 13th and 14th centuries (namely the nave, chancel and tower).

[2] From 1451 to 1842, Ash Green, like the rest of the parish of Exhall, formed part of the Liberty of Coventry, which was geographically in the hundred of Knightlow in the county of Warwickshire, but administratively separate.

Following the abolition of the Liberty of Coventry, the city boundary was revised, with the parish of Exhall (and therefore Ash Green) excluded.
