Located on a remote mountainside in the Peloponnese, the Temple of Apollo Epicurius at Bassae is a well-preserved and unusual Greek temple. It was built somewhere between 450 and 400 BC. The temple is aligned north-south, in contrast to the majority of Greek temples which are aligned east-west. The temple is unusual in that it has examples of all three of the classical orders used in ancient Greek architecture. Doric columns form the peristyle while Ionic columns support the porch and Corinthian columns feature in the interior. The temple of Apollo Epicurius is presently covered in a tent in order to protect the ruins from the elements.
