The Polish historian Stanisław Herbst states in the 1967 "Polish Biographical Dictionary" that Kościuszko may be Poland's and the world's most popular Pole ever. There are monuments to him around the world, beginning with the Kościuszko Mound at Kraków, erected in 1820–23 by men, women, and children bringing earth from the battlefields where he had fought. The Thaddeus Kosciusko Bridge, a twin bridge structure across the Mohawk River in Albany, New York, completed in 1959, and the Kosciuszko Bridge, built in 1939 in New York City, were named in Kościuszko's honor. The New York City bridge was partially replaced in April 2017 by a new bridge of the same name, with an additional bridge that opened in August 2019.
