The structure has no roof, leading the "The Illustrated London News" to call it hypaethral; however, "The Civil Engineer and Architect's Journal" considered this adjective inappropriate. It asserted that "n 'hypoethral' temple does not mean one without any roof at all... but only that peculiar kind of temple in which the "cella" was left partly uncovered"—the monument has no cella. "The Athenaeum" called it "not only hypaethral, but hypaethral "in issimo"—and after the most extraordinary fashion", and remarked, "Possibly it was at first intended that there should be a roof, but in order to save expense, it was afterwards thought that such covering might be dispensed with". According to the council, the monument was indeed originally intended to have a roof and interior walls but these were never built due to a lack of funding. However, "The Chronicle" has reported that this is a myth and a roof was never planned.
