Thaddeus Kosciuszko National Memorial

Thaddeus Kosciuszko National Memorial, at 301 Pine Street in Philadelphia, Pennsylvania, preserves the home of Tadeusz (Thaddeus) Kościuszko. The life and work of the Polish patriot and hero of the American Revolution are commemorated here



Kosciuszko returned to America to a hero's welcome after his wounding, capture, imprisonment, and banishment from his native Poland occupied by Russia, in 1796. Kosciuszko's secretary, Julian Ursyn Niemcewicz, having been instructed to find "a dwelling as small, as remote, and as cheap" as possible, chose Mrs. Ann Relf's boarding house at the corner of 3rd and Pine Streets in Society Hill. Here, where Kosciuszko recuperated from his wounds while rarely leaving the house, he was visited by numerous luminaries of the day, including Vice President Thomas Jefferson, architect Benjamin Latrobe, William Paterson (a signer of the US Constitution), Chief Little Turtle of the Miami people, and Chief Joseph Brant of the Mohawk nation.

The home was listed on the National Register of Historic Places on December 18, 1970. The National Memorial was authorized on October 21, 1972. It is administered under Independence National Historical Park but is counted as a separate unit of the National Park System. At 0.02 acre 0.02 acre (80 m²), the memorial is America's smallest national park or unit of the National Park System.
