The House of Black Heads (Estonian Mustpeade maja) is a Renaissance-style building in Tallinn old town. The building's name is derived from its developers, the Brotherhood of Black Heads which was the guild of foreign unmarried merchants. The Brotherhood was founded sometime around 1399 and was active in Estonia and Latvia.
A 14th-century residential building probably occupied this site when the Black Heads bought up the property in the early 1500s. They immediately installed a new hall with an archless ceiling, but the serious rebuilding got underway in 1597 when the Dutch Renaissance façade, with its profusion of ornaments and carved decorations, was added. The eye-catching front door dates to 1640.
Inside you can see a two-naved, vaulted hall, which bought from the neighbouring St. Olav's Guild and dates to the 15th century. The site is frequently used for concerts and other gala occasions, and naturally any event held here will take on a timeless quality.
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.
