A flamboyant rose window stands out on its Gothic-Mudejar façade.
It is a 13th-century Gothic church. It has a rectangular plan and 3 naves without a transept and 3 apses. At the end of the building, there is a tower on the left-hand side and, alongside the outside naves, there are various chapels. Within the church, the 15th-century mural paintings, the 16th-century chapels decorated with tiles (one of them created by Ruíz de Luna) and the tomb of the Loaysa knight are outstanding.
