The first mentions of the village of Zdunowo date back to 1398. The name of the village was originally written differently. In the “Diplomatic Code of the Duchy of Mazovia”, Zdunowo is listed as Sdunowo, in other documents we find Zdvnowa or Zdunów. In the mid-15th century, Zdunowo was a noble village belonging to the Zdunowski family of the “Junosza” coat of arms, who took their surname from the family estate. In 1584, they divided the estate between the brothers Jakub and Piotr, but Jakub gave part of three fields to his younger brother Piotr. 

In 1782, the estate was purchased by Tadeusz Czerski, a colonel of the Crown Army cavalry. The next buyer of Zdunów was Feliks Golański of the “Jastrzębiec” coat of arms, chamberlain of King Stanisław August, who was still its heir in 1797. We do not know anything about the owners in the 19th century, from that period only two maps of the Zdunowo and Załuski manor farms prepared in 1843 and 1873 have survived.

At the beginning of the 20th century, the vast Zdunowski estates became the property of Cecylia and Stanisław Jaworowski of the “Lubicz” coat of arms. They were the founders of the palace. This is evidenced by the family coat of arms located on the front elevation of the building and the initials “SC” and “J” placed on the entrance door. 

The palace was built on the site of a brick manor house that was once the seat of local gentry. Designed in the style of modernized late baroque, it impresses with its sophisticated architecture. The designer probably belonged to the circle of the Viennese architectural studio Fellner & Helmer. The construction work was carried out in the years 1905-1910 by a team of bricklayers under the supervision of master Kwiatkowski from Strużewo, a village belonging to the Jaworowski estate. The Jaworowskis commissioned the development of a park layout for their residence to the outstanding Warsaw garden planner Walerian Kronenberg. 

The Jaworowskis’ daughter brought the palace as her dowry and thus Piotr Domański became the owner of Zdunów, who unfortunately died in the September Campaign.

During the September Campaign, a field airport was set up in Zdunów for 9 Karaś reconnaissance aircraft. Later, the Germans set up a field hospital there. In 1946, under the decree on agricultural reform, the estate was taken over by the State Treasury. Initially, Soviet troops were stationed there, then the Polish Army, and then the State Children’s Home was located there. In 1957-58, the squatters were removed and the palace was renovated for the needs of the Basic Agricultural School, which was placed here together with the boarding school. At that time, the roof tiles were replaced with galvanized sheet metal. Engineer Ryszard Pawłowski became the school’s director, and his son Michał gave us valuable information about that period. Among other things, he mentioned a bathtub on the roof, in which the owner of the palace used to bathe before the war. The planting of trees from that period resulted in the loss of the original park layout. In 1979, the Horticultural School was closed, and the palace was taken over by the Agricultural Combine in Nacpolsko. On June 1, 1980, the Palace and Park Complex in Zdunów was entered into the register of historical monuments. Despite this, the palace and park were left without any care or maintenance. The unheated and unused building was completely devastated.

In a state of ruin, it was bought in June 1989 by a married couple Julitta Tarnowska and an architect Włodzimierz Mucha. Three years later, the State Agricultural Farm Zdunowo was liquidated. In 2001, the new owners were partners Ireneusz Kostrzewa and Robert Procyszyn, who began a thorough renovation. The building was excavated, the foundations were reinforced, insulation and perimeter drainage were made. In October 2002, a fire completely consumed the roof, the ceiling above the ground floor, the wooden staircases, the door and window joinery. Thanks to Mr. Kostrzewa’s passion, the renovation was not stopped, he replaced the roof again, meticulously recreated the elevation and window joinery, replaced the ceilings above the ground floor, saving the palace from ruin. 

The next owners completed the renovation of the elevation, made a new representative front entrance and a magnificent garden terrace. They replaced the ceilings above the basements, staircases and made a new functional division of the rooms. The door joinery, parquet floors with intarsia and stucco decorations were meticulously restored. These works were supported by the kindness and talent of the Provincial Conservator of Monuments Krzysztof Kaliściak. As a landscape architect, the owner restored the former park layout. Young self-seeds were removed, numerous collectible species of trees were planted, natural monuments were treated, the historic lime tree alley was revalued, the ponds were deepened and the shoreline was reinforced. The area was fenced and received a new Art Nouveau gate. Roads, a driveway, parking lots, granite pavements and a lower terrace were built. After five years of intensive work, on the centenary of its existence, the Zdunowska residence returned to its former glory. In April 2009, the General Conservator of Monuments, Tomasz Merta, awarded the Minister of Culture with an award for the renovation of the Palace in Zdunów.
