The largest statue in New York City’s Central Park is the Status of Polish King Jagiello.

The statue captures a victorious moment in a 1410 battle when King Jagiello, crosses the two swords handed to him by his adversaries, the Teutonic Knights of the Cross (precursors of modern Germany.)
I found one estimate of physical size that listed the base as over ten feet high, and the seated figure on horseback as over fifteen feet high. I don’t live near New York City, so will rely on those measurements. Other descriptions read ‘imposing’ and ‘largest in Central Park.’ If I ever get to Central Park I will look up the statue in person.
I can only imagine that Henry must have been impressed to see such a prominent reminder of his homeland in his new neighborhood. We never discussed it, but now I recognize the photo from his album.
