This church has been recently restored and is interesting to visit. As several others have said, it is in the baroque style and maybe not for everyone. However, you will have missed something if you don’t see it while you’re in Seville. It’s a conversation piece if nothing else. Be sure to visit it before going to the Catedral de Sevilla because the entrance ticket is a dual ticket and it will get you into both. So when you go to the Catherdral, you can bypass the ticket queue, which may be quite long, and go right in.
