At this point the Sacred Way describes a curve and ascends obliquely upwards. Immediately after the curve, on the left, is the Treasury of the Athenians. This is a Doric building, the material of which has largely survived, so that archaeologists were able to restore it entirely supplying only very few additions. (The restoration was made on a grant from the Municipality of Athens, before the Second World War). The pediments and metopes were all decorated with reliefs preserved in sufficiently good condition to permit us to appreciate the Attic sculpture of the late Archaic period. Its precise dating has not been established. Some archaeologists believe that the treasury was built after the battle at Marathon, while others support that it was dedicated by the new Athenian democracy (about 505 - 500 B.C.). The walls of the treasury are covered with inscriptions of later date (3rd century B.C. and later), mostly honorific decrees of Athenians. However, among these inscriptions are two of the most important texts of antiquity: two hymns to Apollo, with the musical notation accompanying the text.
