The Livonian Order's stone castle is the oldest building in Dobele, and a national architectural monument. It was built on the site of an ancient Semigallian timber fortress from 1335 to 1339. A church was built and a park was laid out later.
This land hosted a settlement of Dobele's most ancient inhabitants – the Semigallians as early as 1000 years B.C. Surrounded by the ancient town, there stood a timber fortress, one of the administrative centres of ancient Semigallians. The castle has been mentioned several times in the Livonian Rhymed Chronicle telling about the 13th century battles between the locals and the German crusader knights. Between 1279 and 1289, Dobele castle withstood six enemy attacks. In 1289, the Semigallians burnt down their fortress and left, undefeated, for Rakte in Lithuania.
Until 1562, the castle was headquarters for the chief of the garrison and also the Komtur, commander of the district. During the period of the Duchy of Courland and Semigallia, several commanders were in charge of the castle, the last one being Christoph Georg von Ofenberg. After 1729, the castle built by the Order was abandoned and gradually fell in ruins. Works for the conservation of the ruins started were launched in 2002.
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.
