* Columned facades: Both Greek and Roman temples featured columned facades, with the number of columns increasing with the size of the temple.
* Pediments: Greek and Roman temples also had pediments, or triangular gables above the columns, which were often decorated with sculptures.
* Entablature: The entablature was the horizontal band above the columns that ran around the temple. It was typically divided into three parts: the architrave, the frieze, and the cornice.
* Materials: Greek and Roman temples were typically built of stone, with marble being the most common material. However, some temples were also built of wood or brick.
* Function: Greek and Roman temples were both used for religious purposes, such as ceremonies and sacrifices. However, Roman temples were also used for other purposes, such as political and economic assemblies.
* Architectural Orders: Both Greek and Roman architecture employed the three classical orders: Doric, Ionic, and Corinthian. Each order has its own distinct characteristics, such as the shape of the columns, the ornamentation of the capitals, and the entablature.
Additionally, both Greek and Roman architects used vaults and domes to create monumental interior spaces, such as in the Pantheon in Rome and the Hagia Sophia in Constantinople.
Both Greek and Roman architecture had a profound influence on subsequent Western architecture, and their elements and principles can still be seen in buildings today.
