The Polski Ośrodek Społeczno-Kulturalny (POSK) is the Polish Social and Cultural Association in London. (Charity Number 236745).

3rd May National Holiday is a Polish national holiday. It celebrates the declaration of the Constitution of May 3, 1791. Festivities date back to the Duchy of Warsaw early in the 19th century, but it became an official holiday only in 1919. Delisted during the times of the People’s Republic of Poland, it was reestablished after the fall of communism in modern Poland. More on Wikipedia here.
