0 a building, or part of one, that is round in shape, and often has a dome (= rounded roof) on top -- （有圆顶的）圆形建筑物；圆形大厅
The new construction was concentrated on the rotunda and its surrounding buildings: the great basilica remained in ruins.
One major difference with the inside of this church is that there is no main altarpiece in the rotunda area.
It is understood that when demolition takes place the base of the rotundas will be removed and contamination will be dealt with at that stage.
At the top of the rotunda is the dome, embellished with large paintings that illustrate the history of book making.
Its four arms finish in elegant porticoes with pediments under a domed rotunda over which a shining gilded angel holds the cross.
The rotunda is covered by a grassy hill in the background.
The rotunda on the central hill houses the county library and a central cafeteria.
The park features several small rotunda with seating, lawns suitable for picnicking and a trail of interpretive botanical signage.
