In plan the walls surrounding the Acropolis of Sparta form an irregular oblong, terminated to the east and west by two small hills which formed citadels or outlook points. Though no single complete part remains, and in many places the walls are levelled to the ground, the lines can still be traced fairly completely. (Plate VIII. 3.)

At the south eastern corner are the ruins of a Roman Stoa of the Imperial period (A). They shew a series of small compartments (Fig. 1), covered with barrel vaults, ten on either side of three larger central rooms, which are roofed with crossgroined vaults and large semicircular niches at the back. The ground on the north side is as high as the vaults and originally must have formed a terrace overlooking the street on to which the Stoa opened on its south side.
