Not far from me is the East side gallery.
“The Berlin Wall East Side Gallery is a 1.3km-long section of the wall near the center of Berlin. Approximately 106 paintings by artists from all over the world cover this memorial for freedom and make it the largest open air gallery in the world.”
It is currently in very poor condition, the remaining of the wall itself is crumbling away too. There is interest in repairing the remainder of the wall and the artwork, more about that here.
