The construction of the temple (which is also known as the Columns of the Olympian Zeus) was begun in the 6th century AD by Pisistratus and was completed by the Emperor Hadrian in the 2nd century AD. With dimensions of 96 x 40 m, it was the largest temple in the Greek lands during the Hellenistic and Roman periods. It was made of marble from Mount Pentelicus. It had 104 Corinthian columns, of which fifteen are standing today.
