This graceful Ionic temple (late 5C B.C.) juts out in front of the Propylaea, overlooking the Sacred Way. According to the legend, Aegeus, the father of Theseus, believing his son to be dead, threw himself from the rock where the temple is built. Rebuilt by the Bavarian archaeologists of King Othon, it consists of a cella between 2 porticos with monolithic columns which once concealed a statue of Athena victorious. Only the outer frieze contains original parts (eastern and southern sides).
