In the Propylaia stood works of art made by great sculptors, like the statue of the Hermes Propylaios by Alkamenes. The building consisted of a central section flanked by two wings at the sides. The main building featured five openings. The central opening was the widest one, to accommodate the passing through of the Panathenaic procession and sacrificial animals.  

The north wing had an anteroom and a spacious hall known as the Pinakotheke. This was probably a recreation area with paintings on the walls and couches with tables, where visitors could rest. The south wing had to be reduced, perhaps due to the temple of Athena Nike.
