There are several ruins encircling the Temple of Olympian Zeus. These obscure sites can be hard to identify. In the north are Themistoclean Wall (470 BC), a basilica (5th century) and a Roman bathhouse (131 AD). Below a 3rd century wall to the south are the remnants of the Parilissia Sanctuaries (or Parilissia Iera). They included the Temple of Delphinium Apollo (5th century BC), the Temple of Artemis Agrotera (440 BC), the Sanctuary of Cronus and Rhea (2nd century AD), the Sanctuary of Panhellenic Zeus (2nd century AD) plus the Epi Delphinio Courthouse (5th century BC).
