Long Wittenham
The village Cross has First Millennial origins: the base dating from the 7th century. St. Birinus preached here when he brought Christianity to the area. The Church of England parish church of Saint Mary, begun around 1120, is on the site of a previous Saxon church.  Cruck Cottage can be architecturally dated to being around 800 years old and as such is (possibly) the oldest house in South Oxfordshire.
