The city of Athens deserves to be explored on foot. The agora of Caesar and Augustus lies to the east of the main agora area. The monumental Doric propylon for this space still stands at the west end of the agora. The inscription shows that the gate was dedicated to Athena Archegetis; it is dated to the archonship of Nikias, i.e. 11/10 or 10/9 BC. The architectural style evokes the 5th century Athens of Perikles.
There is an open colonnade inside the propylon, some 111 m long.
