Since 1983, the International Youth Library has been housed in Blutenburg Castle in the Obermenzing quarter of Munich.

The historical building complex dating from the 15th century offers a place to work and study for 32 full and part-time staff members as well as users of all ages speaking many different languages. The underground cellar beneath the castle courtyard provides an extensive storage area for the unique book collection. With the arrival of the International Youth Library, Blutenburg Castle became a «Book Castle», as represented in a vignette drawn by the Leipzig graphic artist Egbert Herfurth.
