Sicyonian Treasury

The Treasury of the Sicyonians is a 6th-century BC structure within the sanctuary of Apollo at Delphi[1]. It replaced two earlier buildings—a tholos and a monopteros—erected by Sicyon earlier in the same century[1]. These earlier structures were commissioned by the Orthagorid dynasty to commemorate victories of tyrant Cleisthenes during the First Sacred War[1]. The treasury's replacement marks a significant political transformation in Sicyon[1].
