A multirotor wind turbine (1) comprising a yaw arrangement (6) and a tower (2) is disclosed. A load carrying structure comprises first and second arms (3) extending from the yaw arrangement (6) and carrying energy generating units (4). the yaw arrangement (6) comprises an outer wall part (7) arranged coaxially with the tower (2) and forming a closed ring extending circumferentially about an outer surface of the tower (2), thereby forming a space (8) between the tower (2) and the outer wall part (7). The outer wall part (7) and the outer surface of the tower (2) are rotatable relative to each other.
