The Krasiński Palace is located in the New Town, at 5 Krasińskich Square. The palace was built in the years 1677-1682 according to the design of Tylman van Gameren, for the Voivode of Płock, Jan Dobrogost Krasiński. Is considered to be one of the most outstanding examples of modern architecture in Poland. At its back there is the Krasiński Garden - municipal park with an area of 11.8 hectares. Currently, the palace houses special collections, i.e. old prints, manuscripts, graphics, cartography and musical items owned by the National Library. The palace interiors are not open to the public on a daily basis. It houses warehouses and conservation workshops for historical collections. Sightseeing is only organized from time to time. Every year, guided tours are organized on the occasion of Jan Kochanowski's name day, which is usually on the weekend adjacent to June 24.
