Rachal Elmerum was assigned to William the Good who gave it as a gift to the Monastery of Santa Maria della Scala famous in those years for the veneration of a sacred image of the Virgin. The devotion was so deep that Rachal took on the name of the cenoby becoming fief of Scala. In the next centuries, the State territory of Rameth , the modern Rometta, which governed the fief of Scala, was divided into two new fiefs entrusted to two noble knights : Giovanni La Rocca and Giovanni Mauro from whom Rocca and Marojanni respectively derived their names.. In 1500, the Peloritan area was struck by violent earthquakes which destroyed Rocca too: the church and other religious and civil buildings were damaged.

It should have been necessary to rebuild the “ Casale” but Gilberto Pollicino, the noble who had inherited the fief, decided to sell all his possessions to an aristocratic Aragonese family: The Valdinas. With the Valdinas the town achieved its highest splendour : a castle was built and around it the fabric of the city destroyed by the earthquake. The founder of the family was Andrea Valdina, but above all one of his descendant, Pietro Valdina was an outstanding historical figure for his merits and his courage,obtaining many privileges among which the changing of Maurojanni in Valdina and of Rocca in the modern Roccavaldina. In the second half of the XVIII century, the Valdina's family begins an inevitable decline. The last descendant, Giovanni, sold his title of Marquis in 1776. Only after Giuseppe Garibaldi's arrival, the pride of the town, mortified by the Bourbon rule, awoke. Twenty-three inhabitants of Rocca became followers of Garibaldi and contributed at the liberation of the island. After the Unity of Italy, the town was equipped with an aqueduct, sewerage and a system of carbide lighting.

However, the economic development caused the growth of small villages that very soon asked for their own autonomy. So, Torregrotta first and Valdina in a second time, came off from Roccavaldina turning into autonomous municipalities. Nowadays, Roccavaldina is a lovely small town having a great touristic inclination and able to increase the value of its rich historical and artistic patrimony, and traditions without ignoring the necessary modernisation of the Urban centre and of its territory.
