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 the United States in August 1797 to a hero's welcome after his wounding, capture, imprisonment, and banishment from his native Poland, which was partitioned by three neighbouring powers. 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. He returned to Europe the following June to support the restoration of a divided Poland. 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 (80 m), the memorial is America's smallest unit of the National Park System. The site is currently open for touring, Saturday and Sunday, from 12:00 noon to 4:00 p.m. No fees, tickets, or reservations are required to visit this site.
