Lists of largest dome structures
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 diameter dome of its time is listed.
Notes:
- Each structure is only described in detail once (the appearance closest to the top of the page), even if it appears on multiple lists. A link to the row where the structure is described in detail is provided.
- The dimension given is the inner diameter (also called inside diameter, or clear span). The thickness of the dome is not included. If the inner diameter of a dome is not available, a footnote follows the structure's name.
- 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.
- 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 listed in small text below.
- These lists exclude structures that are not self-supporting, such as The O2 in London which is 365 m (1,200 ft) in diameter but is supported by masts.
- The name of a structure used is the name it had when it was constructed or first opened. This is particularly relevant regarding stadiums.
