The Palace in Otwock Wielki was constructed as a summer residence for Bieliński family. The construction started after 1682 at the initiative of Kazimierz Ludwik Bieliński and it was accomplished in about 1689, possibly under supervision of Tylman Gamerski, Carlo Ceroni or Józef Fontana. The main tympanum was adorned with a scene of bacchanal with nymphs, satyrs and God Pan in the center.
The subsequent owner, Franciszek Bieliński, Grand Marshal of the Crown renovated the palace in 1757. The modernization in Rococo style was conducted by Jakub Fontana. At that time the interior was remodelled and adjusted for the purpose of a yearlong living - tile stoves were installed instead of fireplaces in some rooms, the outdoor staircase was demolished and a new one was constructed inside. Also new outbuildings were constructed to house guest rooms, kitchens and rooms for servants.
