Abstract
A domed structure having a retractable roof comprises an inside field area, a ringed structure vertically provided around said field area, two tracks laid out on the top of said ringed structure and two movable semi-vaults travelling separately on said two annular tracks, which are put one over the other when the roof is opened and are located in opposite relation to each other when the roof is formed, thereby providing a domed roof as a whole. The annular tracks laid out on the top of said ringed structure may have a gradient rising with respect to the direction of solar radiation.
