Two buildings are said to have been built during Ramiro I's reign, one was a church dedicated to the Virgin Mary and the other construction was a palace. These were built just outside Oviedo, on Monte Lignum. The church Santa Maria de Naranco seems to originally have been a palace, but later repurposed into a church. The church has an atypical plan from other churches at its time, possibly because it was supposed to contain a throne room for the king. The other church built during Ramiro I's time was San Miguel de Lillo.
