The Asturian Pre-Romanesque Openwork Window: Exterior Architectural Detail of San Miguel de Lillo (9th Century)

2610

Created during the Asturian Pre-Romanesque period (Ramirense style), specifically dated to c. 842–850 AD (commissioned during the reign of King Ramiro I of Asturias).

Architecturally, it serves as a clerestory/wall window designed to filter natural light into the elevated tribune level of the royal palatine church while providing structural ventilation and displaying intricate geometric symbolism.
