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.
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.
The unfluted Ionic columns rise from the ground floor and carry a pediment.
