The Plaza de Alfonso II el Casto, known to everyone as Plaza de la Catedral, is located in the historic center of Oviedo. It is one of the emblematic places since it receives its name from the first pilgrim on the Camino de Santiago, according to writings dating from the IX century.

Among the buildings and monuments that surround the square, it is worth highlighting the Church of San Tirso, the Balesquida Chapel, the Rúa palace, the Llanes house or the monument to the Regenta in memory of the character from the novel. by Leopoldo Alas Clarín
