Immeuble Clarté is an apartment building in Geneva designed by Le Corbusier and Pierre Jeanneret starting from 1928 and built in 1931-32. It has eight storeys and comprises 45 free plan units of diverse configurations and sizes. It is one of Le Corbusier's key early projects in which he explored the principles of modernist architecture in apartment buildings, which later led to the Unité d'Habitation design principle.
After it escaped demolition in the 1960s, the building was first renovated in the 1970s. After being again threatened with demolition in the early 1980s, in 1986 it was listed as a historic monument. In July 2016, the building and several other works by Le Corbusier were inscribed as UNESCO World Heritage Sites.
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.
