One of Ephesus' star attractions and second only to the Library of Celsus, this ornate, Corinthian-style temple honours Trajan's successor and originally had a wooden roof when completed in AD 138. Note its main arch; supported by a central keystone, this architectural marvel remains perfectly balanced, with no need for mortar. The temple's designers also covered it with intricate decorative details and patterns: Tyche, goddess of chance, adorns the first arch, while Medusa wards off evil spirits on the second.
