The Braaid in central Isle of Man, with remnants of a Celtic-Norse roundhouse and two longhouses, c. 650–950 AD The Braaid (known by locals as Rumpy) is an Iron Age roundhouse and two Norse long houses on this site represent its occupation until the 11th or 12th century AD in the parish of Marown in the Isle of Man. The site uniquely brings together buildings of Iron Age and Viking styles that were used together and survive down to the present.
