Tidö is one of Sweden's best preserved Baroque palaces, built in the Dutch Renaissance style. The first building on the site was a medieval house built by the Gren family in the 15th century. In 1537, the Gren family sold the castle to the Queen consort, Margaret Leijonhufvud. In 1540, her husband, king Gustav Vasa, traded the castle to Ekolsund Castle and Tidö came to the Tott family. Today, minor ruins of the former house can be found next to the present building.
The present castle at Tidö was built by the Lord High Chancellor of Sweden Axel Oxenstierna in 1625–1645. The castle was built around a rectangular courtyard with the main building to the north and the three linked wings to the east, west and south. The main entrance is through a vault in the south wing. In 1889, the von Schinkel family bought Tidö and they still own it today. Today visitors may see the Toy Museum.
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.
