The exhibition “Water mark. One year after the flood” is presented from September 5 to October 5, 2025, at Central Square in Warsaw. The flood that struck southwestern regions of Poland in September 2024 was one of the largest disasters in recent years. Polish Humanitarian Action was there from the very beginning. We witnessed how needs changed, responded to the most urgent ones, and prepared long-term recovery plans. The exhibition showcases photographs from places affected by the flood, which still bear the marks of that difficult time.
