The Stoa of Antigonus was built around 250 B.C. by Antigonus Gonatas the King of Macedonia, as stated on the architrave inscription: "KING OF KING ANTIGONOS DIMITRIOY MACEDON Apollos." On the Doric entablature, triglyphs alternate with embossed heads of bulls. The statue of Gaius Villiinou proconsul of the Romans gives an idea of the height of the gallery and how the sanctuary would look like with the hundreds ofdedicative statues.
