The Numismatic Museum of Athens: The Numismatic Museum of Athens, originally founded in 1829, is one of the rarest of its kind in the world, with a collection of more than 60,000 rare coins, dating from the period of Greek antiquity, the Roman and Byzantine era, the Middle Ages of Western Europe and up to Modern times. The Numismatic Museum is housed in a 19th century neo-classic building called "Iliou Melathron" (which means the Palace of Ilion), designed by the famous German architect Ernst Ziller.
