Thaddeus Kosciuszko National Memorial

The Thaddeus Kosciuszko National Memorial is a small residence in Philadelphia's historic district where the Polish military engineer lived after returning from war. The house features a restored bedroom on the second floor with period furnishings from his era.

The building at Pine Street became significant in 1797–1798 when Kosciuszko lived there after returning wounded from fighting for Polish independence. His stay marked a crucial connection between the American and European struggles for freedom.

Kosciuszko received visits from Thomas Jefferson and other prominent figures of the era while recovering in this residence. The rooms reflect the connections between European and American leaders during the late 1700s.

The memorial is open only on weekends from April through October with free admission for all visitors. Since the building is quite small, it's wise to check hours in advance to plan your visit accordingly.

The memorial is one of the smallest places in the entire American national park system, fitting neatly within a single historic townhouse. Despite its tiny footprint, it holds a significant story about international struggles for freedom.
