Pointed bulbous domes characterized by a distinctive tapering bulb or onion shape that has a diameter greater than the drum upon which it is placed, and typically having a height that exceeds its width. Onion domes first saw widespread use in Islamic architecture in about the 8th century, when they often topped minarets or were placed over the central space or on the corners of mosques and domestic buildings in the Middle East and India. They were then used in Russia, Spain, Austria, Bavaria, and Eastern Europe by the 18th century; use spread to other Western styles and locations in the 19th century. For small domes, often resembling overturned cups or pointed, and placed over a turret, use "cupolas."Puntige bolvormige koepels.尖頂球根狀圓頂，外觀為獨特的尖形球根或洋蔥形狀，其直徑大於下方之鼓座，高度通常亦大於寬度。洋蔥圓頂最初盛行於西元八世紀左右的伊斯蘭建築，在中東及印度地區，經常位於清真寺的尖塔上，或置於回教寺院及居家建築的中央或角落上方。至十八世紀前，俄羅斯、西班牙、奧地利、德國巴伐利亞及東歐等地亦紛紛使用。在十九世紀則影響了其他西式建築風格與地區。至於設置於塔樓上，類似翻轉的杯子或尖頂的小圓穹，則稱之為「圓屋頂」。
