Due to its good state of preservation, the Temple of Concordia is ranked amongst the most notable edifices of the Greek civilization existing today. Notably the UNESCO symbol alludes to this temple 6 column facade. It has a peristatis of 6 x 13 columns built over a basement of 39.44 x 16.91 m; each Doric column has twenty grooves and a slight entasis, and is surmounted by an architrave with triglyphs and metopes; also perfectly preserved are the tympani. The cella, preceded by a pronaos, is accessed by a single step; also existing are the pylons with the stairs which allowed to reach the roof and, over the cella's walls and in the blocks of the peristasis entablature, the holes for the wooden beam of the ceiling. The exterior and the interior of the temple were covered by polychrome stucco. The upper frame had gutters with lion-like protomes, while the roof was covered by marble tiles.
