The Church of England parish church of St Helen is partly ancient. John Marius Wilson described it as "variously late pointed Norman and decorated; has a modern tower; contains a Norman font and two brasses; and is very good." The parish includes the hamlets of Fifield and Crowmarsh-Battle or Preston-Crowmarsh. The village is often confused with RAF Benson, which is a well-known RAF station and airfield. The RAF airfield boundary is immediately adjacent to the village, and the aerodrome's construction closed the former "London Road". The RAF buildings are on the opposite side of the airfield to Benson village, adjacent to the village of Ewelme.
