Church of St. Isidoro the Royal (Oviedo)
Even though it is only half of what was originally planned, it's well worth your while to visit this parrish.
The solitary tower.
Amongst so many pre-Romanesque buildings throughout the region, it is unusual to find this Baroque edifice. Construction started in 1578 on what was to become a Jesuit college; after their expulsion it went on to become a parrish church, which it has remained to this day. Located on Constitution Square, originally it was larger, but currently part of its structure has been taken over by the market. Like the nearby cathedral, it boasts only one tower even though, according to historical records, the initial plan was to have two. Since 2004, an image of Saint Isidoro found in the church's attic has been on display.
