On the north end of the island, overlooking the sea, stand the ancient remains of the Acropolis of Rhodes. The buildings of the Rhodes Acropolis date back to the 3rd-2nd century BC. Though the entire Acropolis has yet to be excavated, some amazing sections have been restored: the stadium; a marble odeion - a concert hall or theatre; four columns of the Temple of Pythian Apollo; and a few remains of the Temple of Athena Polias and Zeus Polieus.
