A building such as the Monreale Cathedral, outlined by a multiform stylistic syncretism, reflected a deep religious implication promoted by William II. The ruler succeeded in consolidating the Western Christian influence through a fruitful and peaceful dialogue with the Byzantine-Oriental and Muslim-Arab cultures from the very year of his coronation in 1172. Alongside the Cathedral, surrounded by a flourishing natural setting, work began on the foundation of the Royal Palace in the same year, followed in 1176 by the construction of the Benedictine Monastery adjacent to it.
