Despite that its remains include only four columns, the Temple of Castor and Pollux is now the symbol of modern Agrigento. It is in a fact a modern reconstruction from the early 19th century, created using pieces from various other temples. It includes four columns and an entablature mounted over the foundings of an originary temple 31 x 13.39 m, and which would have been a Doric perypteros with 6 x 13 columns, and which dated to about the mid-5th century BC.
