The town dates from Byzantium times.  The castle on the hill was called Castle Euphemius.  When the Moors conquered Sicily, they arabized the name to Kalat al Fimi.  When the Norman reconquest returned the island, the Italianized name became Calatafimi.  Following are pictures of the town from various vantage points during my last two trips in 1998 and 1999.

This is a picture taken from the battlefield, showing the castle on the hill to the left of the picture and the town sprawling off to the right.

This is an old photo of the town of Calatafimi in the 19th Century.  Notice the castle on the top of the hill
and how small the old part of town is.

An even older picture shows a stylized rendition of the castle and town.
