A dome is a feature in structural geology where a circular part of the Earth's surface has been pushed upward, tilting the pre-existing layers of earth away from the center. In technical terms, it consists of symmetrical anticlines that intersect each other at their respective apices .
An oval dome is a dome of oval shape in plan, profile, or both. The term comes from the Latin ovum , meaning "egg". The earliest oval domes were used by convenience in corbelled stone huts as rounded but geometrically undefined coverings, and the first examples in Asia Minor date to around 4000 B.C.

The meaning of the dome has been extensively analyzed by architectural historians. According to Nicola Camerlenghi, it may not be possible to arrive at a single "fixed meaning and universal significance" for domes across all building types and locations throughout history, since the shape, function, and context for individual buildings were determined locally, even if inspired by distant ...

The whole is contained within an imaginary circle which touches each corner of the building and centres of the porticos (illustration, left). The name La Rotonda refers to the central circular hall with its dome.
These units, with most domes raised on drums, became a standard element on a smaller scale in later Byzantine church architecture, and all domes built after the transitional period were braced with bilateral symmetry. [189] The dome over the Church of the Archangels at Sige was replaced in the 19th century, but the original was dated in the ...
The basic design of the Şehzade Mosque, with its symmetrical dome and four semi-dome layout, proved popular with later architects and was repeated in classical Ottoman mosques after Sinan (e.g. the Sultan Ahmed I Mosque, the New Mosque at Eminönü, and the 18th-century reconstruction of the Fatih Mosque).
The first geodesic dome was designed after World War I by Walther Bauersfeld, [1] chief engineer of Carl Zeiss Jena, an optical company, for a planetarium to house his planetarium projector. An initial, small dome was patented and constructed by the firm of Dykerhoff and Wydmann on the roof of the Carl Zeiss Werke in Jena, Germany. A larger ...
