Baroque construction from the late seventeenth century, current headquarters of the House of Culture of Llanes. It is also known as Casa de los Miranda y de los Valdés. The important local politician José de Posada Herrera was born in this palace.
It is a building with three floors and a corner tower with four levels. On the façade, the windows alternate with the balconies, counting on the second floor of the main body with a shield in which the arms of the Posadas, the Pérez de Noreña and the Valdés are represented. Towards the north it has another façade in which another tower rises of the same height as the first, giving way to an elongated two-level body that heads towards the Castle tower, adjacent to the Camino de Santiago.
