Abstract: The invention relates to an enclosure for a pleasure pool, which is completely or partially in the form of a rotunda and which comprises a plurality of rotary angular roof elements. The aforementioned rotary angular roof elements form an angular portion of the rotunda and rotate about the same vertical axis, each element comprising a frame framing at least one cylindrical filler panel. The frame includes a lower circular edge that rests on the ground and an upper edge from which at least two sections extend towards the rotation shaft, which sections join so as, together with the upper edge, to form a frame for an angular portion of the roof-forming filler panel. The roof elements are mounted to rotate about the same vertical axis in order to move between an open position and a closed position.
