The Stoa consisted of a series of 21 chambers, probably shops, faced by a double colonnade, the outer columns being of the Doric order, the inner unfluted, with lotus-leaf capitals; it possessed an upper storey fronted with Ionic columns.
A portion of its western front, adorned with monolith unfluted Corinthian columns, is still standing - the familiar " Stoa of Hadrian "; another well-preserved portion, with six pilasters, runs parallel to the west side of Aeolus Street.
Next in date comes the huge temple G, which, as an inscription proves, was dedicated to Apollo; though it was never entirely completed (many of the columns still remain unfluted), it was in use.
