Always seeing the walls, especially in historical buildings and murals, this question has always triggered me, what are the events and memories they have recorded in themselves. Including: From day one of their construction until now … In my opinion, over time, these walls not only become more beautiful but despite their appearance, they are still strong and stable. Even human and natural destructions are ineffective in their greatness and glory. Vahid Ezzatpanah, March 2020
