Niedermunster Abbey, situated at the foot of Mount Saint Odile was founded around 700 AAD by Saint Odile of Alsace, who was also the first Abbess.
Until the end of the 12th century, the two abbeys formed a single institution, but from the beginning of the 13th century, they began to operate as separate establishments. In 1542 the abbey came under the authority of the Great Chapter of Strasbourg Cathedral.
The Abbey buildings of which the ruins are still visible today were built between 1150 and 1180 AD. The Abbey was seriously damaged during the Peasants' War in 1525 and again by two fires, in 1542 and 1572. The nuns abandoned the abbey in 1545 and it was never reoccupied.
The site was then used, up until the 19th century, as a quarry for other buildings, including the adjacent farm.
For several centuries the abbey was known for its relics, the head and arm of Saint Lazarus of Marseille. When the abbey was burnt down these were transferred to Andlau, eventually disappearing during the French Revolution.
References:The Royal Palace was built in the first half of the 19th century as the Norwegian residence of King Charles III, who also reigned as king of Sweden and otherwise resided there, and is the official residence of the present Norwegian monarch. The crown prince resides at Skaugum in Asker west of Oslo. The palace has 173 rooms.
Until the completion of the Royal Palace, Norwegian royalty resided in Paleet, the magnificent town house in Christiania that the wealthy merchant Bernt Anker bequeathed to the State in 1805 to be used as a royal residence. During the last years of the union with Denmark it was used by the viceroys of Norway, and in 1814 by the first king of independent Norway, Christian Frederick.
