From the 3rd till the 26th of May a series of trial excavations was made along the river bank, north of the precinct of Artemis Orthia. These resulted in the discovery of the Greek wall of the city and of traces of an, at present, nameless Heroön close to it. The following description begins from the south. (General Plan, Pl. VII.)

The part of the wall found south-east of the Artemisium is, as far as it has at present been uncovered, of a normal type (Plate VII.). It is three metres thick, built of hewn limestone blocks laid in courses with irregular jointing. Not more than two courses are preserved, and they rest on a foundation of small stones and rough blocks. Most remarkable is the deep drain running out through the wall, which here comes obliquely from the cliff to the south, between the Roman building and the river. Where the Eurotas has eaten into the bank and destroyed part of the Roman arena, the wall also has been carried away. On the cliff (General Plan, O 16) a few trial pits produced one tile-stamp (of type 17, see p. 348), and revealed a long block of hewn rock, but the line of the fortification has still to be found here.
