Matsumae Castle is a castle located in Matsumae in Hokkaidō, Japan, and is the northernmost castle in Japan. The only traditional style Edo period castle in Hokkaidō, it was the chief residence of the han (estate) of the Matsumae clan.
First built in 1606 by Matsumae Yoshihiro under orders from the Tokugawa shogunate, which required his clan to defend the area, and by extension the whole of Japan, from the Ainu 'barbarians' to the north. It burned down in 1637 but was rebuilt in 1639. It once controlled all passage through Hokkaidō to the rest of Japan.
The present castle complex, which dates from 1854, was constructed to deter attacks by foreign naval forces. Only the 30-metre-high tenshu (main tower) and a gatehouse survived destruction following the Meiji Restoration, which began in 1868. However, the tenshu burned down in 1949 and a concrete replica was built in 1960.
Today, all of the castle site is now a public park. Approximately 8,000 cherry trees are planted in Matsumae Park, which is approximately 150,000 m2 around the site of Matsumae Castle. More than 200,000 people visit the Matsumae Sakura Festival every spring to see cherry blossoms.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
