A nacelle for a wind turbine is disclosed. The nacelle comprises a self-carrying rear structure (1) extending in a length direction (4) between a front end (6) defining an interface towards a hub mounted rotatably on the nacelle, and a rear end (7) arranged opposite to the front end (6), the nacelle defining an interface (15) towards a tower (14) of the wind turbine. The nacelle further comprises at least one pre-tensioned brace cable (8, 9) attached to the rear structure (1) at a first position (10) at or near the interface (15) towards the tower (14) along the length direction (4), at a second position (11) at or near the rear end (7) of the rear structure (1), and at at least one intermediate position (12) between the first position (10) and the second position (11) along the length direction (4). A direction defined by the pre-tensioned brace cable (8, 9) is changed at each intermediate position (12).
