The castle of Buen Amor Monument · Topas, La Armuña, Salamanca Situated in the area of Villanueva de Cañedo, a locality now vanished within the municipality of Topas, this Renaissance castle was built in the 15th century on the initiative of the House of Alba over the remains of an 11th-century fortress, of which the cellar survives. In 1475 the locality and its castle passed to the Catholic Monarchs, and it went on to host Ferdinand the Catholic on his way to the Battle of Toro against the supporters of Juana la Beltraneja. In 1477 it became the property of the Bishop of Ávila, Alonso Ulloa de Fonseca Quijada, who turned it into a palace and residence together with his mistress Teresa de las Cuevas; his constancy in love gave the castle its name, Buen Amor. Declared a historic-artistic monument in 1931, it now operates as a hotel. Photo: El Pantera (CC BY-SA 4.0) What to see and do in Topas
