The Temple of Apollo (Delphi) is central among a number of imposing ruins which are interspersed on the Southern slopes of the Parnassos mountain. This temple of the Doric order was first built around the 7th century B.C by the two legendary architects Trophonios and Agamedes. It was destroyed by an earthquake in 373 B.C and was rebuilt for the third time in 330 B.C. Today, the temple's foundations survive along with several Doric columns made of porous stone and limestone.
