Sieńsko is a village in the Świętokrzyskie Voivodeship, within the Jędrzejów County, situated on the Jędrzejów Plateau in the central part of the Nida Basin. Historically linked to the parish in Trzciniec, the locality lies 18 km southwest of Jędrzejów. Over the centuries, Sieńsko changed hands among various noble families. In the 15th century, it was owned by the Borek family and later by the Kościeniows. In the 16th century, one of the co-owners was Stanisław Borek. Due to its location along the Jędrzejów–Żarnowiec route, Sieńsko held strategic importance. In the 17th century, the village became the property of the Rawicz-Dembiński family, followed by the Białobrzeskis, known for their influential connections. In the 18th century, Sieńsko passed to the Przerębskis and later to the Goczałkowskis, who eventually purchased the estate on a large scale at the end of the century. In the 19th century, the estate was acquired by the Laskowskis, among whom was Kazimierz Laskowski, a poet and expert on rural life. In 1881, the Podgaje folwark (farmstead) was separated, and in 1905 the estate was purchased by Adam Tański. Architecturally, Sieńsko is characterized by an 18th-century manor park, entered in the register of historical monuments, which constitutes an important cultural and historical aspect of the village. Many notable figures associated with Sieńsko have played significant roles in Polish history, and the village stands as a testament to a rich noble heritage as well as political and social changes in Poland.
