St Leonard's, Flamstead is a Grade I Listed church. The building is considered exceptional because it has survived without substantial alteration since about 1450 and contains the most important mediaeval wall paintings in Hertfordshire outside St Alban's Abbey.

Owing to the poor condition of its largely mediaeval roof, the church is currently on the Heritage at Risk Register. A significant community project is under way to secure funds to repair the roof and ensure that the heritage is sustainable for the future. You can read more about this on the Flamstead Heritage project website. At the same time, we hope to provide proper access for those with mobility impairments and modern kitchen, toilet, meeting and office facilities, to enable the building to better serve its community.
