The church of the royal complex

San Miguel de Lillo was built during the reign of Ramiro I (842–850) on the slopes of Monte Naranco, a short distance from Santa María del Naranco. It formed part of the same royal complex and was conceived as a church from the outset.

Medieval sources associate the construction of the church and the royal buildings on Monte Naranco with Ramiro I. The complex is traditionally considered to have been consecrated in the year 848.

A building only partially preserved

The original church had a basilican plan with three naves, separated by arcades resting on columns, and a tripartite east end. A collapse during the Middle Ages destroyed approximately two thirds of the original building.

What survives today is mainly the western section: the vestibule, the royal gallery above it and the first bay of the naves. Archaeological excavations have made it possible to reconstruct the ground plan of the original church.

A key to understanding San Miguel de Lillo: its present appearance does not reflect the dimensions it had in the 9th century. The building that survives today represents approximately one third of the original church.

Architecture and decoration

The church is notable for the verticality of its proportions and for its complex system of barrel vaults. One particularly significant feature is the use of columns to support the arcades that separated the naves, an unusual solution in Asturian architecture.

It also preserves important sculptural decoration. Particularly noteworthy are the entrance door jambs with figurative reliefs, together with capitals, bases and remains of stone latticework. Traces of mural painting also survive inside.
