St. Andrew's Church stands on the ancient circle site, with a chapel known to be located here from 1250. The rounded boundaries of the churchyard imply an underlying mote and ancient meeting place. The ancient yew tree in the churchyard is about 2,000 years old (as estimated by Kew garden's experts) and is the oldest tree in London (also included in the book "100 Greatest Trees of London). The Tithe Barn and the adjacent animal Pound, now both part of the Pound House estate, date from 17th and 16th centuries respectively. In 1790-1791, during the church renovation, all church services were conducted in the Tithe Barn. The West End House barn and Laurel Farm barn were built in the 17th century, and have now been converted into private houses. Timber-framed buildings existing from the Tudor era also include Willow House and Rose Cottage.
