St. Helen's Chapel (also known as the De Appleby Chapel) is the earliest surviving building in the village. It dates from before the early 14th century, but its exact date of construction is unknown. From the mid-14th century it was used as a private chapel for the de Appleby family, Lords of the Manor of Appleby, who resided in the adjacent Manor House (the Moat House). The de Appleby / Appleby Family were Lords of the Manor from the early 12th century until the 16th century.
