| A rotary observation tower. An erected frame has a pair of endless chains wound around chain wheels driven in the same direction at the same speed. Outwardly protruding arms are provided at spaced intervals on the pair of endless chains, and a frame is rotatably mounted on the other end of each arm around a horizontal axis which is parallel with the axis of the chain wheel. A gondola is rotatably suspended from the center of each frame around a perpendicular axis. A guide rail curved so as to constitute a part of a helix is provided on the outside of the erected frame so that the said guide rail will cause the gondola to rotate around its perpendicular axis as it is elevated by means of guiding wheels mounted on the external periphery of the gondola.
