The interior of the Holy Spirit Church in Heidelberg has a beautiful Gothic vaulted ceiling, and in many of the places where the arches meet they have placed heraldic bosses. These bosses are a mixed bag; some of them are very well done, while others are somewhat crudely painted. I’m sure this is fine for most of the tourists they have visit there, but as a heraldry enthusiast - and someone who has a telephoto lens and isn't afraid to use it - I have to admit that I was disappointed in some of them.
Be that as it may, it’s nice to see a good attempt at using heraldry as a decorative element, and I appreciate the effort. I will leave it up to you to decide which ones you think succeed and which ones you think ought to be redone.
