Kiekrz is an administrative estate of Poznań, located at the northwestern edge of the city, near Lake Kierskie, which is the largest lake within the city limits of Poznań. The area of Kiekrz, divided into a "rural" and an "urban" part, is surrounded by three lakes, and its history dates back approximately 8,000 years, with the first mention of the locality from 1386. A small village originally belonging to the knightly Nałęcz family, it eventually became the seat of the Kierski family, owners of a manor and farmstead in the 16th century. From the former Kierski manor, only an 18th-century outbuilding remains to this day, now used as the office of the Rehabilitation Hospital for Children. In the 19th century, Kiekrz came under Prussian rule, and after the end of World War I, it had various owners until it finally became the property of the city of Poznań in 1928, which transformed it into an anti-tuberculosis preventorium for children. During World War II, the facility was used by German organizations, and after the war, it was converted into an orphanage and later an anti-tuberculosis sanatorium. Finally, in 1967, it was transformed into the Rehabilitation Sanatorium for Children, which operates to this day, specializing in pediatric rehabilitation. Kiekrz is also home to the Church of St. Michael the Archangel and the Assumption of the Blessed Virgin Mary. The estate is well-connected, with its own railway station and bus lines. Kiekrz, with its beautiful lakes and nature, is a popular destination for recreation and sports activities, especially sailing. Architecturally, it stands out with its historic buildings and a park that has been renovated and plays an important role in local culture.
