Temple of Apollo Epicurius

The Temple of Apollo Epicurius at Bassae, built 420-400 BC at 1,131 metres elevation on Mount Kotylion in the Peloponnese, is the earliest known temple to combine all three classical orders -- Doric, Ionic, and Corinthian. Attributed to Iktinos, architect of the Parthenon, it features six columns across and fifteen along its length. Forgotten for centuries, it was rediscovered in 1765 and became the first Greek temple inscribed as a UNESCO World Heritage Site in 1986. Its decorative frieze is now split between the British Museum and the National Museum in Athens. A protective tent has covered the site since 1987.
