I do not see what you are talking about. Where is there someone praying to a statue?
Beneath the stained glass windows there is a statue of a man praying to statues. This is the church where Martin Luther is entombed, the 95 Theses were posted on the door to this church, this church more than any other place is where the Reformation BEGAN. And yet this church is full of statues and stained glass depicting the Blessed Virgin and Crucifixes.
So, please explain why these weren't removed if they were so objectionable to Luther. For that matter, those of you who have so many issues with Catholic/Orthodox Marian beliefs should have the same issues with Martin Luther because HE BELIEVED THE SAME THING THAT CATHOLICS DO ABOUT THE BLESSED VIRGIN!
