Bråborg was a former Royal castle at Bråviken. The house was built by Queen Dowager Gunilla Bielke in 1588-1590 and she lived there after her husband, King John III of Sweden, died in 1592. Gunilla Bielke herself died at Bråborg in 1597. Bråborg was later owned by her son, duke John of Östergötland. In 1612 he married his cousin, princess Maria Elisabeth of Sweden. They both died at Bråborg in 1618.
The building was partly destroyed in a fire in 1669, and in 1719 it was burnt down by a Russian army. The army also attacked the nearby town of Norrköping. The inhabitants needed stone to rebuild their town and used building material from the ruins of Bråborg. The new manor house at Bråborg was built about 1,000 metres from the burnt down house.
Today, a ruin is all that remains of the estate. The foundations and cellars are still visible today, together with the moats and parts of the gardens.
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.
