The Hermitage is a cottage orné in Hanwell, London built by rector Dr. George Henry Glasse in 1809 on the site of a previous house called the Elms. Nikolaus Pevsner described the house as "a peach of an early c19 Gothic thatched cottage with two pointed windows, a quatrefoil, and an ogee arched door, all on a minute scale. Inside, an octagonal hall and reception room." It is a Grade II listed building. Behind the cottage lies a spring, which may be the origin of 'well' being incorporated into the local place name of Hanwell.
