Tower of Burón Monument · A Fonsagrada, Fonsagrada, Lugo Remains of a 15th-century medieval fortress in the parish of A Proba de Burón, in A Fonsagrada (Lugo), of which the tower and traces of the wall survive; it gave its name to the Terras de Burón, the old jurisdiction that grouped these mountain parishes. The fortress belonged to the House of Trastámara and around 1458 its rights passed to Pedro Osorio de Villalobos, an irmandiño captain married to Urraca de Moscoso. The local residents, who considered it a heavy tax burden, took it to court, and in 1490 the Real Chancillería de Valladolid issued a ruling, confirmed by the Catholic Monarchs, fixing what they had to pay and the services they owed it. The fortress had been destroyed during the irmandiño revolt of 1467-1469, in which about ten thousand men from Burón and Navia took part, and had to be rebuilt.
