This is a small portion of the giant bronze sarcophagus contains the remains of Emperor Charles VI (1685-1740), the last true Hapsburg ruler in the male line.
@darchibald Thank you. I want to return. I know more and can do so much better if given the chance. No flash is allowed and at the time a tourist guide would briefly use a flashlight to illuminate. This is the only successful shot from this crypt. It's my favorite image of my photography journey. Thanks for the fav 🤍
