De Trompenburgh is a 17th-century manor house designed by Daniel Stalpaert and built for Admiral Maarten Tromp, one of the naval heroes of the Dutch Republic. The house is almost entirely surrounded by water and was built to resemble a ship, even with decks and railings.
Before the current house was built another buitenplaats had been built by Andries Bicker in 1636. The original house dates back to 1654. Through inheritance the house came into the possession of the widow of Van Hellemont Raephorst who remarried on January 25, 1667 with Admiral Cornelis Tromp. The couple redecorated the estate considerably, but the house and their improvements were treasure looted and burned by the French during the rampjaar 1672. It was rebuilt in 1675-1684 by Maarten Tromp's son, Admiral Cornelis Tromp, who called it Syllisburg, after one of his titles. Around 1720 Jacob Roeters came into possession of the estate and he renamed it Trompenburg and had a gilded plaque with an ode by Gerard Brandt in memory of Tromp installed over the entrance in 1725.

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.
