Helena Radziwiłłowa

Helena was born the daughter of Anthony Tadeusz Prezezdecki (1718–1772) and his wife, Princess Catherine Oginska (b. 1725).^[2] After the death of her mother, she was raised by her aunt Princess Aleksandra Czartoryska (1730–1798), the wife of Prince Michał Kazimierz Ogiński.^[3] She received an education and was fluent in French, English, German, and Italian.^[3]

She married Prince Michał Hieronim Radziwiłł (1744–1831) on 26 April 1771. Following the wedding she and her husband lived in Czernawczycy, then Nieborów Palace,^[4] and in the Radziwill Palace in Warsaw.^[3] At the coronation of Paul I, she was made a lady of state and awarded with the Order of Saint Catherine of the lesser cross.

Following fashion and an example from her rival Izabela Czartoryska, who managed an estate at Puławy, Helena founded her own park not far from Neborov. With the help of architects, she designed the romantic parked which she naimed 'Arcadia" Helena would devote 40 years of her life to this park which would become her pride and joy.^[3][5]

The park was designed in the English style, its pavilions were decorated with works of art inspired by Ancient Greece and Rome. In July of 1795, Helena Radziwiłł hosted Zofia Potocka, who was inspired to build her own, the famous Sofiyivka Park.

In the later years of her life, Princess Radziwiłł had lost her former cheerfulness. Having met her in 1818, Princess Varvara Turkestanova wrote of her:^[6]

"The princess is very kind and accommodating. She has changed and aged a lot. This is attributed to the complete breakdown of her condition: The magnificent Arcadia is about to be confiscated... She is in an extremely difficult situation. The unhappy woman is ruined and mired in debt. In addition, she is responsible for the guardianship of the estate of the late Dominic. She is afriand of the outcome of the trial that she is conducting with the Chernyshevs."

She died in Warsaw in 1821.^[3]
