From Ms Wiki: “The Shoes on the Danube Bank is a memorial created by Gyula Pauer and Can Togay on the bank of the Danube River in Budapest.
“It honors the Jews who were killed by fascist Arrow Cross militiamen in Budapest during World War II. They were ordered to take off their shoes, and were shot at the edge of the water so that their bodies fell into the river and were carried away. It represents their shoes left behind on the bank.”
