A listed World Heritage Site since 1985, this former audience chamber turned into a sanctuary was part of the summer residence built by Ramiro I of Asturias in the 9C on the south side of Mount Naranco. The harmonious quadrangular edifice is lit by vast bays. On the upper floor, two loggias open off the main chamber. The interior decoration has been cleverly adapted to architectural necessity with clusters of slender colonnettes, as well as Corinthian and polygonal capitals. Equal attention has been paid to appearances outside.
