Viewed from without, nothing indicates that this edifice is a ruin. Over the entrance are the arms of the Counts of Fuensalida. It is supposed by many that this castle was erected by Garcilaso de la Vega, grandfather of the "Prince of Spanish poets," as the celebrated bard of Toledo is entitled. Others maintain its founder to have been Pedro Lopez de Ayala, first Count of Fuensalida. This latter story is the more probable one; since, besides its being confirmed by the armorial shield above mentioned, it has been adopted by Haro in his Nobiliario, a work drawn up with care and research, in which Garcilaso de la Vega is stated to have purchased some towns from the family of Ayala,--among others Cuerva, in the near neighbourhood, but not Guadamur. The Ayalas were descended from the house of Haro, lords of Biscay. Several of them had held high offices at the Court of Castile. The grandfather of the founder of the castle had been High Chancellor of Castile, and Great Chamberlain of Juan the First; and his father, the first lord of Fuensalida, was High Steward, and first Alcalde of Toledo. He lost an eye at the siege of Antequera,--taken from the Moors by Ferdinand, afterwards King of Aragon, in the year 1410, and thus acquired the surname of the One-eyed. To him Juan II. first granted the faculty of converting his possessions into hereditary fiefs: "Because," according to one of the clauses of the act, "it was just that the houses of the grandees should remain entire in their state for the eldest son; and in order that the eldest sons of the grandees might be maintained in the estates of their predecessors, that the name and memory of the grandees of the kingdom might not be lost, and that the hereditary possessions and houses, and the generations of the sons of grandees might be preserved." It was Pedro Lopez de Ayala, son of the one-eyed lord of Fuensalida created Count by Enrique the Fourth, that built the castle. He was a great favourite with the king, and his constant companion, notwithstanding his being afflicted with deafness--a bad defect in a courtier, and which procured him also a surname. He succeeded his father in his different dignities. His loyalty did not keep pace with his obligations to Henry the Fourth; for, being first Alcalde of Toledo, he made no effort to prevent that town from joining the party of the Prince Alonzo, who pretended to his brother's crown; but he was recalled to his allegiance by the devoted exertions of his wife.
