Lullingstone is the site of one of the earliest known Christian chapels in the British Isles, dating from the 4th century. The mosaics and wall paintings have been well-preserved, offering an understanding of the symbolic nature of early Christian worship.

"The Lullingstone villa can be explained simply as a private house decorated to accord with the aesthetic tastes and religious beliefs of the occupants, but the compact and serviceable unit cut off from the rest of the building seems rather to indicate a house-church used by the local Christians." (Milburn 16)
