Pre-romanesque - Monte Naranco

Today was covid booster day - I had to go to Oviedo for the jab, and took advantage of the opportunity to visit the pre-romanesque churches on Monte Naranco.
The church of Santa María del Naranco and the nearby church of San Miguel de Lillo have both sat on Monte Naranco, less than 3km above Oviedo, since the 9th century. 
I couldn´t get in to either church but I´ve tried to show as much as I can from outside. The main photo is a detail of the external east wall of Santa Maria, showing the altar; and there follow several extras showing aspects or details of the exterior of the church. Then an extra shows the exterior of San Miguel, seen from its south west - it´s a clearly smaller structure, much squarer in shape - and then are shown 3 pre-romanesque windows from San Miguel. The last extra shows a pre-romanesque window on San Miguel, the whole of which was carved from one piece of stone.
I´ll delete most of the extras in a day or two. 
Both churches can be googled for a lot more information.
