Old iron...

This is old ironwork on the south door of the church of San Xuan (or Juan) de Amandi, Villaviciosa. The church is 13th century but the door won´t be. I´ve no idea when the ironwork was made. 
Extras show 1. the complete door,  2 the south wall including the door and a recess - I don´t know what went in the recess,  3. the recess in its wall, showing decorative stonework, and 4, from round the corner on the west entrance, a baptismal font.
