Le Locle is known as a center of Swiss watchmaking, even cited as the birthplace of the industry, with roots dating back to the 1600s. The municipality has been home to manufactures such as Mido, Zodiac, Tissot, Ulysse Nardin, Zenith, Montblanc, Certina as well as Universal Genève, before the latter company relocated to Geneva. The town's history in watchmaking is documented at one of the world's premier horological museums, the Musée d'Horlogerie du Locle, Monts Castle, located in a 19th-century country manor on a hill north of the city. Restored historic underground mills (grainmill, oilmill, sawmill) can be seen in a cave located about one kilometer west of the city center.
The Ancien Hôtel des Postes, Monts Castle and the Museum d’horlogerie, City Hall, the Immeuble, Moulins souterrains du Col-des-Roches (Cave mills in the Col des Roches), the Villa Favre-Jacot and Zenith SA are listed as Swiss heritage site of national significance. It is part of the UNESCO World Heritage Site: La Chaux-de-Fonds/Le Locle, Watchmaking Town Planning (since 2009) and the entire town of Le Locle is part of the Inventory of Swiss 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.
