A tent is provided wherein the poles are a series of stressed, arcuate rods which surround a convex polyhedra such as a hemispherical structure. The arcuate rods are approximately in the configuration of segments of circles and they cross at a plurality of points and fit in sockets at each point of crossing and the crossing point is fastened to the membrane forming the tent.
