PROBLEM TO BE SOLVED: To provide a tower-like structure which exerts the great shaking-reducing effect of enabling the effective reduction of shaking caused by a horizontal external force. SOLUTION: This tower-like structure comprises a tubular structure (core wall 2) which is extended upward from a foundation 5, a tower structure (steel tower 3) which is extended upward from the foundation 5 so as to surround the periphery of the tubular structure, and a damper 4 which connects the tubular structure and the tower structure together. The damper 4 is installed in such a manner as to be vertically inclined with respect to a horizontal plane 11. The damper 4 is equipped with a rod-like body 14 which is formed like a rod from an operating member and a tubular casing, making a relative linear motion. A one end-side attachment portion 17 of one end of the rod-like body 14 and the tubular structure, and the other end-side attachment portion 19 of the other end of the rod-like body 14 and the tower structure are provided in vertically-displaced positions. Thus, the operating member and the tubular casing are attached in such a manner that a direction, in which the operating member and the tubular casing make the relative linear motion, is set as a direction vertically inclined with respect to the horizontal plane 11.
