The term 'ATHENIAN Portico' is a combination of two words: 'STOA' and 'ATHENIAN'. STOA is a four-letter Greek word meaning 'PORCH' or 'COLONNADE'. An ATHENIAN portico is a type of COLONNADE found in ancient Greece, typically constructed from marble and used as a public gathering place. It was often used for political meetings, religious ceremonies, and other public events. The porticos were also used as a form of decoration, with sculptures and other artwork adorning the walls.
