| Description | Portnason was owned by the representatives of Christopher Allingham at the time of Griffith’s Valuation but was unoccupied. The National Inventory of Architectural Heritage suggests it was built in the early 19th century and may have replaced an earlier house, also associated with the Allingham family. It is still extant. |
