A partially self-erecting wind turbine tower and a method for carrying out the assembly thereof. A central extendable pylon is provided. This is placed in an upright position, with its base on a temporary foundation. A plurality of legs is then attached to the extendable pylon. The upper extreme of each of the plurality of legs is temporarily attached to the upper extreme of the extendable pylon. With the pylon and legs thus secured, a nacelle is attached to the upper extreme of the extendable pylon. A hub with attached blades is then affixed to the nacelle. The extendable pylon is then forced upward through the collar to extend the height of the assembly.
