A wind turbine tower configured to support a wind turbine nacelle and a rotor, and with a tower wall of an inner surface and an outer surface. The tower is tethered by a number of cables, each cable extending between a first end anchored to an anchoring element and an opposite, second end attached to the tower at an attachment element. Two cables extending from two different anchoring elements are attached to the tower such that longitudinal projection lines from the second ends of the two cables converge at a convergence point, which lies at a location at a certain height and inside the tower wall thickness. Alternatively, the convergence point lies inside the tower within a distance of three wall thicknesses from the wall inner surface as measured at the height and in a direction perpendicular to the central longitudinal axis of the tower. The invention further relates to a method of erecting a wind turbine tower tethered by cables and configured for supporting a rotor assembly, and wherein the tower comprises a number of tower sections joined to each other. The method comprises positioning a first tower section, attaching at least some of the tethering cables to a second tower section while the second tower section is on the ground, lifting the second tower section with the attached cables onto the first tower section, and joining the second tower section to the first.
