The Green also has two Grade II listed buildings. To the north is the Unitarian Church, which celebrated its tercentenary in 2008. The original 1708 building was financed with £300 from goldsmith Edward Harrison. It was a "substantial brick building, of nearly square form, with the high, tiled, projecting roof, common at its era". "Historic views show that the original façade had a small pediment against a large hipped roof, with a central oval window below." This building was substantially extended and improved in the mid-19th century. An internal gallery was built to increase the seating available, and a few years later the roof and apse were renewed, and a "stuccoed frontage" was built, "mirroring the original façade with a three-bay front with two round-headed windows, but with added Tuscan pilasters and a large pediment". In the mid-20th century, the building was damaged by enemy action. In 1953 its architectural importance was recognised as a Grade II listed building.
