As New York's first public memorial to the Holocaust, Holocaust Memorial Park stands for all time as a somber reminder of the millions of lives lost and the rich culture destroyed. Since 1985, thousands have gathered each year at the Holocaust Memorial Park to share memory, prayer and hope. (Xinhua/Wang Lei)
