About 100 metres south-east of the new bridge over the Eurotas a line of large blocks can be seen in the right bank of the river running out into its bed. These are the remains of the city-wall, which originally must have made a sharp bend to the south-west, as it reappears in the field of the Heroön. But this angle, and the land which it enclosed, have been carried away by a change in the course of the river. Close to the northern arm of the angle, and abutting on the present river-bank, lies the large structure illustrated in Figs. 1 and 2. Its eastern front has long been visible, but seems to have escaped the observation of travellers. Excavation revealed at a depth of 0·70 m. below the present surface, a great platform 23·60 m. long by 6·60 m. wide and 1·90 m. high. There are four foundation courses, averaging 0·34 m. in height, of a softish crumbly stone, and a sillcourse 0·55 m. high, projecting 0·10 m. beyond the foundations. This sillcourse consists of squared and dressed blocks, which extend all round the building with a uniform breadth of 0·90 m., and vary from 1·60 m. to 2·50 m. in length. Their surface is carefully smoothed, leaving an edge on the outside, raised 0·003 m. and 0·07 to 0·08 m. wide. This careful finish, combined with the regularity of the foundation-courses, and the absence of all trace of bonding-mortar, suggests Hellenic workmanship.
