This temple was dedicated to Apollo for his decisive role at Delphi. It is the same width as the Temple of Hera, but only has 6 columns across the front. It was the last temple put together here, and resembles the Temple of Zeus in Olympia (built in 460 BC, ten years after the Temple of Zeus). It is hexastyle Doric peripteral with inner amphi distyle in antis. The inside columns were double tiered with twenty flutes on the lower tier and sixteen on the upper tier. The outside columns had twenty-four flutes. The temple had no sculpture or iconography, but did have classical Doric details like guttae (drops under triglyphs; signifying that nails kept the wooden structure in place).
