A support for a large vertical axis wind turbine including a tower frame, a platform, a vertical central axis, and a vertical axis windmill including a plurality of blades and supporting arms. The platform is disposed on the tower frame for installing and fixing a generator. The vertical central axis and the vertical axis windmill are supported by the tower frame. The tower frame is a truss structure and includes at least three sub-tower frames which are in parallel with each other and form a regular polygon from top view. The sub-tower frames are hollow tubes. The ratio of a diameter of the vertical axis windmill to a distance between two adjacent sub-tower frames is between 2.5 and 6. The ratio of the diameter of the vertical axis windmill to a height of the tower frame is between 3 and 0.5.
