Ostrów Tumski, Poznań

Ostrów Tumski is an island between two branches of the river Warta in the city of Poznań in western Poland. Poznań Cathedral and other ecclesiastical buildings occupy the central part of the island. Ostrów Tumski is part of the city's former Nowe Miasto ("New Town") district, although it is actually the oldest part of the city, where the rulers of the early Polish state in the 10th century had one of their palaces. The site is listed as one of Poland's official national Historic Monuments (Pomnik historii), as designated November 28, 2008, along with other portions of the city's historic core. Its listing is maintained by the National Heritage Board of Poland. In the current administrative division of Poznań, Ostrów Tumski is part of an osiedle which also includes the neighbourhoods of Śródka, Zawady and Komandoria, all on the east side of the river.
