The construction of the castle was begun in the 12th century by Pietro and Ridolfo del Grifo. Later, Malatesta da Verucchio captured the Grifo tower, which became the mastio of the current castle, which was to be finished in the 15th century.
After the Malatesta seignory, the town was conquered by the Sforza in the September 1289. Here, in 1494, arrived Lucrezia Borgia, wife of Giovanni Sforza. After a short domination of Lucrezia's brother, Cesare, Gradara was handed over to the della Rovere. After the end of the latter's dynasty, the city was administrated directly by the Popes.
