From the 15th century on , Sicily was reigned by the so-called vice kings . Between 1412 and 1515 , Adrano was under administration by the Moncada family . Giovan Tommaso Moncada ( 1466 – 1501 ) renovated the Norman castle and fortified it . He allowed a couple of refugees from the northern Greek region of Epirus to settle down in the vicinity of Adrano , which is how the town of Biancavilla was founded . The relatives of earl Moncada build many manors ( so-called '' palazzi '' ) in the centre of the town , among which is the latter town hall , and the centre of the city , the '' piazza '' , became popular meeting place for the residents , who meanwhile numbered around 6,000 . Around the same time began the construction of the Monastero di Santa Lucia ( Monastery of St Lucy ) . In 1693 , a severe earthquake inflicted heavy damage to the town
