Because there exists no complete survey or accurate record of the important ruin of Roman date commonly known as the Stoa of Hadrian, it has seemed worth while to make a detailed examination and conjectural reconstruction of the remains in order to settle, if possible, the still disputed question of identity and, with the aid of relevant literary material, to throw further light on the purpose and history of the structure.
The ruin in question lies in the lower part of the modern town at the foot of the northern slope of the Acropolis and slightly to the north of the Roman Agora and the Gateway of Athena Archegetis. Between the streets of Ares and Aeolus lofty walls, in part preserved, enclose on three sides a rectangular space, half of which has been excavated, revealing the foundations of an internal colonnade or stoa and various rooms, while the remainder is occupied by roads, houses, shops, barracks and a military prison. The wall on the fourth or southern side is unexcavated, but it is evident from the disposition of those now visible that the building was symmetrical about an axis running approximately east and west. The only entrance to the enclosure was in the west wall, which was of marble and decorated with columns of the Corinthian order. Of this façade only the northern half and one column of the entrance portico are now visible. On the north, east, and doubtless on the south, the area was enclosed by blank, rusticated walls of limestone.
