Ohtu manor (Ocht) traces its origins to at least the 17th century. The manor received its current late baroque appearance, possibly the work of architect Johann Schultz, in 1769. The manor suffered from being neglected and eventually abandoned during the 20th century, but has been restored in 2002-2004. Some original details, such as the rococo carved wooden main door and a fine sculpted ashlar fireplace from 1654 (possibly the work of Joachim Winter of Haapsalu), are preserved in the house. Today the manor is in private ownership.
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.
