PROBLEM TO BE SOLVED: To provide a high-rise tower capable of highlighting the extensity and symbolic value thereof and displaying different aspects when viewed from different sides, and having a rich and varied design which has not been found before. SOLUTION: This high-rise tower T comprises two HP shells 10a, 10b using steel piping. The two shells 10a, 10b are converged upward by forming. Each of the two shells 10a, 10b is so formed that the outer peripheral surface is formed in a hyperbolic paraboloid by a plurality of straight steel pipes 1 and has a top point 10c of generally triangle when viewed from above which is formed generally vertical to the parabolic shape from the lower side toward the upper side. The bottom-side sides of the generally triangle when viewed from above of the shells 10a, 10b are opposed to each other at an interval while setting the top points 10c of the generally triangle when viewed from above of the shells 10a, 10b on the outside.
