Malla manor traces its history back to 1443, when it is first recorder in written sources. During that time, there was a small castle at the site. Around 1620, the estate became the property of Swedish field marshal Gustav Horn. In 1651-1654, he commissioned architect Zakarias Hoffmann to erect a new manor house on the site. The house burnt down during the Great Northern War, and the current building received its appearance in the 1880's. The estate is now privately owned.

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.
