Parham Old Hall, also known as Moat Hall, is a moated site and historic medieval mansion close to the village of Parham, in Suffolk, England. Closely associated with the Barons Willoughby of Parham, it is a Grade II listed building on the National Heritage List for England and includes the remains of a formal garden. The site is a scheduled monument with remains of a 15th- and 16th-century hall on its central island.[1][2] A gateway that featured heraldic shields of the Willoughbys was dismantled and shipped to America in 1926. There is in the locality another unconnected building known as Parham New Hall.
