After 711, in the period of dominance of the Iberian Peninsula by the Moors, the Christian Kingdom of Asturias (c.711–910), located in the Northern part of the peninsula, was a centre of resistance (see "Reconquista"). In addition, many Christians (Mozarabs) lived in Moorish territories and were allowed to practice their religion and build churches. Asturian architecture and Mozarabic art influenced Christian buildings in the future Portuguese territory, as seen on the few structures that have survived from this time. The most important of these is the Church of São Pedro de Lourosa, located near Oliveira do Hospital, which bears an inscription that gives 912 as the year of its construction. The church is a basilica with three aisles separated by horseshoe arches, a narthex on the façade and mullioned, horseshoe-shaped windows of Asturian influence on the central aisle.
