On of the best preserved temples of the greek world is the temple of the Concordia, which was built around 440/430 BC. The temple is surrounded by columns (six on the fronts and thirteen on the long sides), enclosing a closed cell in which was kept the statue of the deity, preceded by a vestibule and followed by a rear compartment, both with two columns in the front. The pillars held up an entablature, with the typical decoration of the Doric temple, characterized by the alternation of smooth and grooved plates (metopes and triglyphs). In the Christian era (VI century. A.D.), the temple was transformed into a Christian church, through the opening of the arches in the walls of the cell and the closing of the spaces between the columns.
