 The Branicki Palace previously had been called the "Mrs Krakowska Palace", because after Branicki's death the property was inherited by his beautiful wife Izabella Poniatowska (1771), sister of king Stanisław August Poniatowski (Izabella was a daughter of Stanisław Poniatowski, Castellan of Kraków).She held a salon in the palace, and became known as a patron and gatherer of artists, intellectuals, and statesmen in the era of Enlightenment in Poland.Shortly afterwards the Branicki Palace was sold in 1804 to the general Józef Niemojewski.
