Castillo de Villalonso stands in the Zamora province of Castile and León, representing a prime example of the Valladolid school of 15th-century castle architecture. This medieval palace-fortress was rebuilt following the architectural style characteristic of border fortifications constructed between Valladolid and Palencia during the 1400s. Part of a broader defensive system including the castles of Mota del Marqués and Torrelobatón, the structure has been restored since 1984 and is considered among the best-preserved castles in Zamora province. Now open to visitors with guided tours available, the venue also accommodates special events including weddings.
