The invention provides a linear rotating tower for a mountainous area. The rotating tower comprises a tower head, a tower body and tower legs from top to bottom, and a conversion layer is arranged between the tower head and the tower body, so that the tower head can rotate relative to the tower body. The tower head can rotate by a certain angle relative to the tower body, so that the front connecting line of the tower legs is parallel to the mountain slope or the side connecting line of the tower legs is perpendicular to the mountain slope, thereby adapting to tower position topographic conditions; the tower erection of a certain limited tower position becomes possible, and a whole line path scheme is established; and the line length is reduced, the ratio of the strain tower is reduced, the engineering investment is reduced, operations such as foundation construction evolution are reduced, and the environment is protected.
