The battlefields of Toro Historical milestone · Peleagonzalo, Alfoz de Toro, Zamora Image of Peleagonzalo, not of the place itself. The fields of Peleagonzalo, on the bank of the Duero between Toro and the Zamora provincial capital, with its municipal boundary entirely surrounded by that of Toro, were the actual scene of the clash of 1 March 1476 between the troops of the Catholic Monarchs and those of Afonso V of Portugal and his son, Prince John; the battle remained undecided on the ground, with a Portuguese victory on one flank and a Castilian one on the other, but it morally decided the Castilian war of succession by representing a great political victory for Isabella and Ferdinand, which secured the throne for Isabella and the union of the crowns of Castile and Aragon. 1476 Photo: File:Les_plantes_cultivades._Cereals_(2008).djvu: Miquel Pujol Palol derivative work: Joancreus (talk) (CC BY-SA 3.0) What to see and do in Peleagonzalo
