The estate complex of the 18th-19th centuries of the Gansky family in Verkhovna - a national architectural monument - included a park, a palace, an outbuilding with a kitchen, a manager's house, a greenhouse, a pond with swans, a zoo corner and a church-tomb. The two-storey Empire-style palace with columns was built in 1800 by the Italian architect Blériot. Count V. Gansky presented the estate to his wife Evelina in 1819, shortly after their wedding. Hence Evelina, one of the most beautiful women in Poland, from 1832 kept secret correspondence with Honore de Balzac. They tied the knot in 1850, when Evelina had been a widow for several years.

Now part of the palace is occupied by an agrotechnical college, and since April 1959 an exposition dedicated to Honore de Balzac has been opened here. The museum includes 3 rooms that the writer used in 1847-50: an entrance hall, a study and a bedroom. The table at which Balzac wrote several works, an 18th-century piano, a sideboard, a chandelier and some other items used by the famous Frenchman has been preserved.
