The Kammerzell House is one of the most famous buildings of Strasbourg and one of the most ornate and well preserved medieval civil housing buildings in late Gothic architecture in the areas formerly belonging to the Holy Roman Empire.
Built in 1427 but twice transformed in 1467 and 1589, the building as it is now historically belongs to the German Renaissance but is stylistically still attached to the Rhineland black and white timber-framed style of civil (as opposed to administrative, clerical or noble) architecture.
It is situated on the Place de la Cathédrale, north-west of the Strasbourg Cathedral, with whose rosy colour it contrasts in a picturesque way when seen from the opposite direction.
The building's inside has been decorated on all floors by lavish frescoes by Alsatian painter Léo Schnug (1878-1933). It now houses a restaurant.
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.
