Blutenburg Castle is an old ducal old country seat in the west of Munich, Germany. It was built on the banks of river Würm by duke Albert III in 1438–39 as a hunting-lodge, replacing an older castle burned down in war. Albert's son duke Sigismund of Bavaria extended the castle from 1488 onwards and died here in 1501. He also ordered to construct the late-Gothic palace church, which still keeps the altars of Jan Polack. The main building was destroyed during the Thirty Years War, but it was again rebuilt in 1680–81. The castle still is surrounded by a ring wall with four towers. Since 1983 the International Youth Library has been housed in Blutenburg Castle.
