Norse settlement on the isle is generally accepted to have been founded by Magnus Barefoot circa 1098 who probably built a timber fort or 'Peel' and established a royal residence for the Norse Kings of Man. The latter has been partly evidenced by excavation at the Earl of Derby's Apartments where a 12th century, two-phase, domestic building, including one sophisticated floor, and a burial ground containing an important female burial or 'queen', have been discovered.
