In 1198 the abbot of Hornbach Abbey granted two hills, the Gutinberc and the Ruprehtisberc, to Count Henry I of Zweibrücken. On these hills the count built the castles of Lemberg and Ruppertstein. The construction period was probably around 1200, but the first documented record of the Castrum Lewenberc dates to 1230. Today, all that survives on the Schlossberg hill are some wall remains and the foundation of a chapel. The chapel was mentioned in 1502, but coins and shards of pottery found on the site indicate that it goes back to the second half of the 13th century.
In 1333 the castle went to Count Simon I, son of Eberhardt of Zweibrücken-Bitsch. From 1535 to 1541, his successor, Count James of Zweibrücken-Bitsch resided at the castle and remodeled it into a Renaissance schloss. Following his death in 1570 an inheritance dispute arose, which the Lehnsherr of the castle, Duke Charles of Lorraine ended by occupying the castle with his own troops in 1572. In 1606 he agreed with Count John Reinhard I of Hanau-Lichtenberg, that James' grandson would receive the Lemberg estate, whilst Charles II would hold the lordship of Bitche.
The castle and village were occupied and plundered in 1634 and 1635 during the Thirty Years' War. In 1636 the castle was razed and then only rebuilt in makeshift fashion.
In 1688 Louis XIV of France sparked the War of the Palatine Succession. He acted on the authority of his sister-in-law, Liselotte of the Palatinate. The background was his plans for expansion, which were opposed by an alliance of the German emperor, the imperial princes, Spain and England. In view of their superiority, Louis XIV, ordered that the Palatinate was to be burned. French troops probably slighted the castle in October 1689; even the bergfried was demolished.
From then on, the location no longer held any military significance. The wall remains continued to decay, usable stone was carried off and employed for other purposes, for example, the rebuilding of a village church in 1746. Since the 20th century, the castle ruins have gained in importance as a tourist attraction. In 1953, the Lemberg branch of the Palatine Forest Club renovated the castle and established a café; and since 2001 a modern extension has been built to act as a castle information centre and centre for medieval events.
One feature of Lemberg Castle is its shaft cistern, also, but not quite correctly, called the well shaft. After digging down 94.80 metres the well diggers had still not struck the ground water. So the shaft was turned into a cistern and almost horizontal adit driven to the shaft. After almost 200 metres the adit meets the shaft at a depth of about 60 metres. A spring on the hillside filled the shaft via the adit thus providing the required water supply. All the work was carried out with hammers and chisels. It is also remarkable that the tunnel ever intercepted the shaft. The well proved to be a valuable archaeological site during several excavation projects in the 1990s, especially for the period of the destruction of the castle in the 17th century.
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.
