List of largest domes

A dome is a self-supporting structural element of architecture that resembles the hollow upper half of a sphere.

Every dome in the world which was the largest (by diameter) dome of its time is listed below.

Notes:


 * 1) Each structure is only described in detail one time on this page (the appearance closest to the top of the page), even if it appears in multiple lists. A link to the row where the structure is described in detail is provided.
 * 2) The dimensions given are inner diameters (also called inside diameters, or clear spans), meaning the thickness of the dome itself is not included. If the inner diameter of a dome is not available, a footnote follows the structure's name.
 * 3) If a dome has an elliptical rather than circular shape, the dome's shorter dimension (i.e. width) is used for ranking, and, contra convention, its dimensions are listed as width × length, rather than length × width.
 * 4) If the structure is part of a well-known complex of buildings, the name of the entire site is listed first, with the name of the dome structure itself listed in small text below.
 * 5) These lists exclude structures that are not self-supporting, such as The O2 in London which is 365 undefined in diameter but is supported by masts.
 * 6) The name of a structure used is the name it had when it was constructed or first opened. This is particularly relevant regarding stadiums.
