In ancient Greek architecture, a propylaea, propylea or propylaia (/ˌprɒpɪˈliːə/; Greek: προπύλαια) is a monumental gateway. The prototypical Greek example is the propylaea that serves as the entrance to the Acropolis of Athens. The Greek Revival Brandenburg Gate of Berlin and the Propylaea in Munich both evoke the central portion of the Athens propylaea.
