Dina and Clarenza are two women connected in legend with the historical siege of Messina by Charles I of Anjou during the Sicilian Vespers in August 1282.
The Vespers rebellion, begun in Palermo on Easter Monday, 30 March 1282, outside the Church of the Holy Spirit, spread quickly all over the island.
Charles laid siege to Messina in vain until September, and in his attempt to conquer and occupy the city he spared no civilians, not old people, nor women, nor children.
While Dina continually hurled rocks down on the enemy soldiers, Clarenza rang the bells in the campanile of the Duomo, from which she awakened the whole city.
Today, Dina and Clarenza are found portrayed in Messina at Palazzo Zanca (the city hall) and on the campanile of the Duomo.
