HISTORY
The remotest roots of Caltanissetta are as yet
uncertain. Relics from the Bronze Age and several cave-sepulchres seem to
attest to prehistoric settlements. Some historians held that the city origins
might be somehow related to the ancient Nissa, situated on a mount called Gibil
(or Gabel). The earliest documented information goes back to the Norman
conquest, dated 1086, when Count Roger took the Castle of Pietrarossa. A
remarkable urban development was recorded in the 15th century,
Caltanissetta extending its territory beyond the city walls.
