This is a difficult site to visit, since it’s only open seasonally, on weekends, in the afternoon, in an area with very little parking. The site is tiny, consisting of a few displays, a short film, and this recreation of his room in a boarding house here in Philadelphia. So, why do we have a site for a Polish citizen?

Thaddeus left Poland and arrived almost simultaneously with the British fleet at the outbreak of the Revolutionary War. He had military education and soon found himself employed as an engineer. Long story short, Kosciuszko was the one who chose the site and designed the fortification at Saratoga, which became the turning point of the war. He also designed and oversaw construction of the fort at West Point, which was deemed impenetrable by the British. He also joined the southern campaign and even fought in the last skirmish at the end of the war.

He returned to Poland, declared independence from Russia, and was wounded and exiled when his insurrection failed. The site here is also considered a Polish historic site. He lived in the room above for many years and was close friends with many American Revolutionary War leaders, including Thomas Jefferson. He asked Jefferson to use his American pension to free slaves through his will, but somehow the case eventually lost in court. Jefferson may have been the wrong person to entrust for that.
