Who is this Pieta Lady at Amtsgericht Mitte?

When I brought my letters to the curt (Amtsgericht Mitte) at Littenstrasse, I had the chance to make some pictures of the great panorama inside the building. 

 When I left there, we're two artists asking me If I could make a picture in front of the Pieta sculpture at the monastery of the Franziskaner next to the curt. They're wearing this colorful woke pants suits. I asked them if they are also doing the "artistic participation" for Berlin now and if they have a social Media Platform. They told me that it's all coming. I offered them to put the pictures on Google Maps, which I have not done because the algorithm of Google has a bug and Sergey Brin better calls his mother to fix it.
The two artist and me also laughed about the fact that everyone in Berlin has to dance around the places in Berlin to promote the city. We agreed that it is stressful. Well, it was nice though to share this artistic moment and coloration at this very special place. Have you seen this place or this Woman already ?
