Gewerkenegg Castle dominates the Idrija city. It was erected at the beginning of the 16th century to serve as the administrative headquarters and warehouse of the Idrija mine, then the second largest mercury mine in the world. The now beautifully restored Renaissance complex experienced a Baroque renovation in the middle of the 18th century when the inner arcaded courtyard was created and painted with attractive decorative frescoes.
The castle now houses the Idrija Museum, whose central exhibit-Five Centuries of Mercury Mining and the Town of Idrija-offers a survey of the half-millennium history of the oldest mining town in Slovenia. It also offers an exhibit of Idrija lace, a replica of a room in an Idrija miner's home, peasant frescoes, memorial rooms of the writer France Bevk and the politician Aleš Bebler, and a collection of paintings donated by the gallery owner Valentina Orsini Mazza. The castle also provides rooms and a concert hall for the Idrija Music School. Throughout the year, the museum organizes various events, presentations, and receptions in the castle hall. The Museum Evenings lecture series is especially popular. In summer, the Castle Evenings program of cultural events, mostly concerts, moves into the castle courtyard.
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.
