Jadwisin is a picturesque village in Poland, located in the Masovian Voivodeship, within the commune of Serock, on the shores of the Zegrze Reservoir. It is characterized by its recreational nature, offering a wide range of opportunities for water sports, tourism, and fishing. The village lies within the boundaries of the Warsaw Protected Landscape Area, and its surroundings include two nature reserves: the reserve at the Radziwiłł Palace and the Szaniawski Ravine Reserve. Together, they form a valuable natural area rich in unique ecosystems. The most important architectural monument in Jadwisin is the Neoclassical Radziwiłł Palace, built between 1896 and 1898, which impresses with its unusual structure, topped with a mansard roof. The palace is surrounded by an extensive park with preserved fragments of the Serock Primeval Forest and currently serves as the Training and Recreation Center of the Chancellery of the Prime Minister. Another interesting site is the ruins of the Szaniawski Manor, which burned down in 1977 and was the creative workplace of the renowned playwright Jerzy Szaniawski. It was here that works such as "The Paper Lover" and "The Lawyer and the Roses" were written. Jadwisin is also home to a statue of St. Stanislaus Kostka, created by the sculptor Ludwik Kauffman in the first half of the 19th century. Interestingly, the area was also known as a summer retreat for social elites in the 19th century and for the activities of a Gypsy caravan, which was the pride of the village. The village also features sailing marinas and sailing clubs, as well as a branch of the Institute of Horticulture and Plant Acclimatization. Archaeological discoveries indicate that the area was inhabited as early as the Bronze Age and the period of Roman influence, confirmed by finds of ceramics and coins dating from the 2nd century BCE to the 3rd century CE. Jadwisin is a place that combines natural wealth, history, and architecture, while offering a wide range of opportunities for recreation and relaxation.
