For the construction of the monumental facade of his palace, Don Pedro, a Christian king, counted on Muslim craftsmen who had remained in a territory that was already of Christian rule, they were called Mudejars. Islamic art was then admired, even among members of other religions. Thus, Pedro I asked his friend the Nazari sultan of Granada Muhammad V, ruler of the Alhambra, to bring him the best artists who were working there, who, in collaboration with Mudejars, created this great work in which Christian and Muslim elements are combined: Islamic schematic vegetable decoration of Muslim taste mixed with shields of Castile, Leon and the Order of the Band, alluding to king Don Pedro.
Regarding hybridization, the frieze that crowns the windows of the central body of the façade stands out. In it there is a beautiful inscription in Arabic made of white and blue ceramic where the motto of the Nasrid of Granada repeats, "And no victor but Allah", surrounded by another in Castilian language (Spanish) associated with Christianity, where the door tells the visitors that its builder was "the very high and very noble and very powerful conqueror Don Pedro". They coexist in the same space, without excluding, Christian and Muslim.
Just as there is a survival of the arts of Islamic tradition, it can be also noted a continuity of the Muslim taste for gardening in times of certain Christian kings during the Spanish Low Middle Ages. Andalusí culture could continue like that under the policy of coexistence raised by monarchs like this Pedro I.
