An extraordinary piece of funerary art, befitting two of Poland's most powerful, wealthy and influential families, this tomb in Wilanów Park was dedicated to Stanisław Kostka Potocki and his wife Aleksandra (nee Lubomirska) Potocka by their son Aleksander. Designed in 1834 by Henryk Marconi and built between 1834-1836 by Jakub Tatarkiewicz and Konstanty Hegl, the mausoleum is made entirely of sandstone. Consisting of a Neo-Gothic canopy with lions holding shields bearing the crests of the Potocki and Lubomirski families in each corner, on the sarcophagus itself are the figures of the deceased, and around the sides symbols of their virtues and interests are displayed.
