<p>An onion dome (Russian: луковичная глава, lúkovichnaya glava; compare Russian: лук, luk, "onion") is a dome whose shape resembles an onion. Such domes are often larger in diameter than the drum upon which they sit, and their height usually exceeds their width. These bulbous structures taper smoothly to a point.
</p><p>It is the predominant form for church domes in [Russia] (mostly on Russian Orthodox churches) and in Bavaria, Germany (German: Zwiebelturm (literally "onion tower"), plural: Zwiebeltürme, mostly on Catholic churches), but can also be found regularly across Austria, northeastern Italy, Eastern Europe, Mughal India, the Middle East and Central Asia.
