Most of the cities have museums preserve the artifacts,
such as sculptural reliefs, statues, ornaments, domestic
utensils, frescoes and mosaics. Besides these, the ruins
of the period still standing, exhibit their treasures
as an open-air museum. The most memorable of these are;
Pergamum, on the Aegean coast, with its wide streets bordered
by Corinthian Temple of Aphrodite, and Ephesus, columns,
with its amphitheaters, and with its world famous Temple
of Artemis; one of the seven ancient wonders of the world.
