Marquisate of Aitona Historical milestone · Aitona, Segrià, Lleida Image of Aitona, not of the place itself. The title of baron of Aitona, originally granted by Peter the Catholic to his illegitimate daughter, the infanta Constanza of Aragon, passed by marriage to the Montcada family, in whose hands it remained for nearly five centuries. Charles I raised it to a county in 1523, and in 1581 the title was raised to a marquisate in favour of Francisco de Montcada y de Cardona, lieutenant of the Principality and of Valencia; in 1670 Charles II granted the grandeeship of Spain to Miguel Francisco de Montcada. The seigneurial jurisdiction extended, besides Aitona, to Seròs, Vila-seca and Algorfa, and its holders occupied viceroyalties and embassies of the Hispanic monarchy; in 2018, with the succession of the fourteenth marchioness in the female line, the title passed to the German princely house of Hohenlohe-Langenburg, based in Madrid. 1581 Photo: Amikoj (CC BY-SA 4.0) What to see and do in Aitona
