Castillo Palacio de los Ribera in Bornos originated as an Arab fortification around the 10th century, becoming the nucleus around which the city developed. Rescued during the Christian reconquest circa 1250, it was purchased by Per Afán de Ribera in 1398, marking the beginning of the Ribera family's prominent role. The structure exemplifies the transition from medieval fortress to Renaissance palace, with the current splendor owing to 16th and 17th-century transformations inspired by travel to Jerusalem. The castle features an elegant courtyard surrounded by pointed-arch cloisters, upper galleries with ogival balustrades, and a marble fountain bearing the Ribera coat of arms, crafted by Italian and Spanish artists contracted by the family.
