Portico

Citation: http://en.wikipedia.org/wiki/File:Acropolis_of_Athens_01361.JPG Portico-the porch of a building that has a roof held up with columns. The portico is the entrance of the building. A very famous example is the entrance of the Pantheon in Greece. The number of columns determine the name of the portico. Tetrastyle means it has four columns. Because these are smaller structures, they are used for public buildings. During the archaic period, hexastyle porticos were common with Doric columns such as the Temple of Athena.
