San Tirso el Real
San Tirso el Real was founded in the 9th century by Alfonso II the Chaste and formed part of the early royal and religious complex built around San Salvador. Although the church was extensively altered over the centuries, its east end preserves one of the most recognizable remains of Asturian Pre-Romanesque architecture.

A church from the Oviedo of Alfonso II
San Tirso el Real was founded in the 9th century by Alfonso II the Chaste and formed part of the early royal and religious complex built around San Salvador. Located only a few metres from today’s Oviedo Cathedral, it stands in the heart of the medieval city.
The building underwent major transformations over the centuries, with alterations in different periods. As a result, the church seen today combines elements from several eras and preserves only part of its original Pre-Romanesque fabric.
The Pre-Romanesque east end and triple-arched window
The main surviving feature of Alfonso II’s church is preserved in the east end. High on the wall is a distinctive triple-arched window formed by three brick arches resting on marble columns with capitals of Roman tradition, all framed by a rectangular moulding resembling an alfiz.
This feature is the most recognizable image of San Tirso and links the church architecturally with other buildings from the reign of Alfonso II, including San Julián de los Prados, San Pedro de Nora and Santa María de Bendones.
Centuries of transformations
San Tirso underwent successive alterations that substantially changed the original building. The present church reflects different stages of Oviedo’s religious architecture, from the surviving Pre-Romanesque east end to elements added during later renovations.
This historical layering makes San Tirso different from Oviedo’s other Pre-Romanesque monuments: its importance lies not in preserving a complete 9th-century church, but in incorporating into a living place of worship one of the architectural witnesses to the first capital of the Kingdom of Asturias.
Protected cultural monument
The church of San Tirso el Real was declared a historic-artistic monument in 1931, a form of protection now corresponding to Spain’s Bien de Interés Cultural (BIC) status. Although it preserves an important example of Asturian Pre-Romanesque architecture, San Tirso is not part of the “Monuments of Oviedo and the Kingdom of the Asturias” inscribed on the UNESCO World Heritage List.
