The invention relates to an improved access to the bearing of a wind turbine rotor blade. A rotor (1) of a wind turbine, comprises a rotor blade (2a, 2b) and a hub (3), whereby the rotor blade (2a, 2b) comprises a root end (4) and the root end (4) is attached to a rotor blade bearing (5), and the rotor blade bearing (5) is attached to the hub (3). The rotor blade (2) comprises a root section (6), adjacent to the root end (4), comprising the outer surface of the rotor blade (2a, 2b). The root section (6) of the rotor blade (2a, 2b) is covered by a housing (7). The housing (7) comprises a wall section (8) that leads at least partially circumferentially around the root section (6) of the rotor blade (2a, 2b). The housing (7) comprises a cover section (9) to at least partially close the gap between the wall section (8) of the housing (7) and the rotor blade (2a, 2b). The housing (7) defines an aisle (10) that leads circumferentially around the root section (6) of the rotor blade (2a, 2b) to provide access to the
