Aalborghus is a half-timbered castle built by King Christian III from 1539 to around 1555 initially as a fortification. Soon it became the seat of the king's provincial governors in Northern Jutland, and after the introduction of absolutism, became used by the State County of Northern Jutland for taxes.
A building had pre-existed at the site before Christian III's castle. It stood south of the castle and is mentioned in the first documentation of Aalborghus, dating back to 1340. It was owned by Margrethe I and was the death place of King Hans in 1513 who died in a horse riding accident.
Frederick I had originally intended to destroy the initial building around 1530 and moving to a different site to convert Aalborg's Franciscan monastery into a castle. However he left the decision to his son Christian III, who later decided to demolish the original in 1539 and contracted the royal architect Morten Bussert to build a new fortified castle north of the old site, near the Liim Fjord. A barrier wall was built alongside the fjord, and later in 1633, Christian IV built a north wing facing the port, which was used as a granary for the storage of food supplies such as corn. A western wing was built to the same effect later, holding other supplies such as meats and fish.
The southern facing wing was created between 1808 and 1809 but all that remains today of the original castle is the east wing. Between 1954 and 1964 the old granaries underwent full renovation by the Royal Inspector of Listed Buildings, Leopold Teschl, who converted them into council offices.
References:The Clementinum is a historic complex of buildings in Prague. 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.
