Santa Cristina de Lena

St Christine of Lena is a Roman Catholic Asturian pre-Romanesque church located in the Lena municipality, about 25 km south of Oviedo, Spain, on an old Roman road that joined the lands of the plateau with Asturias.
The church has a different ground plan to Pre-Romanesque's traditional basilica. It is a single rectangular space with a barrel vault, with four adjoining structures located in the centre of each facade. The first of these annexes is the typical Asturian Pre-Romanesque vestibule, with a royal tribune on the upper part, accessed via a stairway joined to one of the walls. To the east is the enclosure with the altar, with a single apse, foregoing the traditional Asturian pre-romanesque triple apse, and going back to Visigoth influences. To the north and south respectively, there are two other enclosures through semicircular arches and barrel vaults, whose use was associated with the Hispano-Visigothic liturgy practised in Spain up to the 11th century.
