Val-Saint-Lambert Abbey was a Cistercian abbey in the Prince-Bishopric of Liège. The foundation of the abbey is attributed to Hugues de Pierrepont, Bishop of Liège. The construction began in 1202 after he gave a tract of land and woods situated in what was then called the Champ des Maures to a group of monks. The abbey was a daughter house of Signy Abbey in Ardennes, France.
Val-Saint-Lambert Abbey was inhabited by a religious community for centuries; it prospered and became powerful. The abbey's chateau served as the summer palace of the Prince-Bishopric of Liège. The abbot Simon de Harlez began an expansion project in 1750, funded by his coal earnings. It was completed before 1796 when the monks were expelled as a result of the French Revolution, at which time the buildings were demolished and the holdings were sold as public goods. In 1825, the abbey ruins were purchased by the chemist François Kemlin and the engineer Auguste Lelièvre, who converted the building into a glass works. Since 1826, it has been used by the crystal manufacturer Val-Saint-Lambert. In 1846, Val Saint-Lambert merged with the Société Anonyme des Manufactures de Glaces.
Several original buildings from the ancient abbey remain, such as the 13th century Chapter House and the 17th century House of Outsiders chateau, built in Mosan style, which houses the crystal museum. The 18th century abbey entrance serves as Seraing's Tourist Information Office. The structure is considered to be an important example of Cistercian architecture as well as Gothic architectural development in Belgium.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
