Stop war stay together

A big one, covers almost entire back of the building. Accessible from the path not from the street. The building is abandoned and half-ruined. Art covers several walls, to fully appreciate its beauty you have to see more than just the front, it is also worth to go up the stairs (it's safe).
Art is brand new painted in July 2024, fresh and vibrant letters says "FREE STAN" and "Stop war stay together".
