Church of San Tirso, Oviedo

The Church of Saint Thyrsus is a Roman Catholic Asturian Romanesque church situated in Oviedo, in Asturias, northern Spain. The church was established in the 790s. Dedicated to Saint Thyrsus, it was built by Tioda, the royal architect of Alfonso II of Asturias. The Great Fire of Oviedo in 1521 and rebuilding in the 18th century removed most of the original church, except for a three-light window.
