Kórnik Library

The Kórnik Arboretum in Kórnik, in western Poland, is the largest and oldest arboretum in Poland and fourth-largest arboretum in Europe, with over 3300 taxa of trees and shrubs. It was established in the early 19th century around the historical Kórnik Castle by its owner, Count Tytus Działyński, later enriched with new species and varieties by his heirs, his son Jan Kanty Działyński and grandson Władysław Zamoyski.The arboretum covers over 40 hectares (99 acres) and is famous for rich collections of rhododendrons, azaleas, magnolias, conifers, lilacs, apple trees, cherries, meadowsweets, honeysuckles, poplars, birches, and other woody species from all over the world. Old specimens of native and alien trees and shrubs can be seen there, such as lindens, beeches, oaks, maidenhair trees, arborvitaes, spruces, and firs. The Institute of Dendrology of the Polish Academy of Sciences is located within the arboretum. In 2010, a 3.5-kilometre long educational trail called Trees of the World was opened in the arboretum. It enables visitors to see and obtain botanical information on 25 major species of trees found in North America, Asia and Europe.

Bnin [bnin] (German: Seebrück) is part of the town of Kórnik, south-east of the city of Poznań, in Greater Poland Voivodeship in western Poland, between Lake Kórnickie and Lake Bnińskie. From 1395 to 1934, Bnin was a town in its own right. It became part of Kórnik in 1961. Near Lake Bnińskie, there are remnants of an ancient fortified settlement. Probably princes of Greater Poland (Wielkopolska) owned it. Later on, the town was the ancestral home of the Bninski family (coat of arms: Łodzia). In the 15th century, Andrzej Bniński, Bishop of Poznan in 1438–1479, was the heir of the town. He erected there a stone church. In 1775, Lady Teofila Potulicka from the Dzialynski family (the heiress at that time) completely rebuilt the church. In the late 19th century, the town was composed of 126 homes, with about 1300 inhabitants: 263 Evangelicals and 1040 Catholics. It was the only town in the Grand Duchy of Poznań without a Jewish population. Most of the inhabitants were occupied with agriculture. There was an elementary school, a post office, and four market places. Bnin belonged then to the Działyński family then.
