The two most interesting monuments in the district are the ancient churches of Santa Maria de Naranco and San Miguel de Lino, both outside the walls. The former was rebuilt by Ramiro I., and is, therefore, well over a thousand years old. Attached to it were a palace and baths, every trace of which has long since disappeared. The architecture presents curious local peculiarities. The church is situated on a slope, and is composed of a single nave resting on a crypt or substructure. The only entrance is by a porch on the north side, which is on the level of the nave and approached by steps. The whole exterior is severe and simple, strong buttresses running up the walls to the sloping roof. In the west front three stages may be distinguished: the lowest is formed by the substructure entered in the middle by a round arch; above this the nave terminates in a portico of three round arches, which spring from four palm-like pillars with Corinthian capitals; in the middle of the third stage is a window of three lights, also round arched. The interior has remained practically unchanged since Ramiro’s day. The chancel and choir occupy opposite ends of the nave, and are raised by one and three steps respectively above the level of the flooring. Both are shut off by three round arches, the middle one being higher than the others; and an arcade of closed arches runs along the side-walls of the nave. These arches are rudely constructed, and rest upon, rather than spring from, octagonal capitals, quaintly carved with figures of priests and lions. The columns are composed each of four engaged shafts, of the same pattern as those of the western portico. The ribs of the waggon-vaulted ceiling spring from corbels, beneath which are reliefs representing the two orders of society in Asturias in the ninth century--knights engaged in combat, and toilers carrying loads. Under these again are circular medallions, filled with conventional foliage, and having in the centre reliefs of lions and birds. The church was probably intended to be open at both ends, as it is now, that the congregation assembled on the hillside might be able to assist in divine worship. It is one of the most valuable architectural monuments of Spain.
