The Temple of the Delians or Grand Temple is the latest and largest of the three temples dedicated to Apollo. It is a "peripteral" Doric temple with six columns on each of the narrow sides and thirteen on each of the long ones. Its construction began in 478 B.C. but stopped around the middle of the 5th century B.C., when the League' s treasury was transferred to Athens. Work was resumed later on, during the period of Delian independence, but was never actually finished.
