During the High Middle Ages the Freiherr von Rümligen owned a vast swathe of land between the Gürbe and Sense rivers. The first appearance of the family in the historical record is in 1076 when Lütold von Rümligen founded Rüeggisberg Priory. By the 13th century they were allied with Bern and in 1320-21 Berchtold von Rümligen (1294-1337) was the Schultheiss in Bern. The Simmental and Summerau lines of the Rümligen family eventually split off and gained extensive lands of their own.
In 1380 the Sommerau-Rümligen family merged back into the main line and inherited the land when Alisa von Rümligen married Peter von Sommerau. In 1388 the Freiherren came under Bernese control, though they continued to own the estates for another century and a half. Gilian von Sommerau-Rümligen was the grandson of Peter and a bailiff in several Bernese cities. He was also a Bernese captain in the Battle of Nancy in 1447. However, his descendants quickly became impoverished and sold the Herrschaft of Rümligen to Bern for 370 pounds. The last Freiherr von Rümligen died unmarried in 1579.
By the 17th century a series of Bernese patrician families owned Rümligen. After passing through a couple of owners, in 1634 Johann Rudolf von Erlach bought the castle and estates. His grandson sold it in 1680 to Ferdinand von Wattenwyl. They sold the castle to Samuel Frisching who passed it on to his son Samuel Frisching (II) when he died in 1683. In 1709 Samuel Frisching (II) built a new Baroque castle around the medieval core. Frisching had a distinguished career. In 1712 as the head of the Bernese War Council he commanded the Protestant Bernese troops to victory in the Toggenburg War. In 1715 he was elected Schultheiss of Bern, an office he held until his death on 23 October 1723.
Following the 1798 French invasion and the creation of the Helvetic Republic the owners of the castle retained it by lost their manorial rights over the villagers. Rümligen remained with the Frisching family until the marriage of Alette Sophie Rosine Frisching to Friedrich von Wattenwyl von Bursinel in 1838. Following the death of their son, Friedrich von Wattenwyl in 1877, the castle was inherited by Dr. Ludwig Moritz Albert Tscharner who often lived at the castle until his death in 1927.
The medieval tower is still visible above the castle, though it was given a Baroque mansard roof in the 18th century. It is possible that the medieval castle was built on or included a much earlier, Roman era watch tower. The residential wing to the south of the tower is probably also medieval, but was extensively rebuilt at the same time. The tower and wing partly enclose a garden and courtyard which were cut into the hill side.References:
Glimmingehus is the best preserved medieval stronghold in Scandinavia. It was built 1499-1506, during an era when Scania formed a vital part of Denmark, and contains many defensive arrangements of the era, such as parapets, false doors and dead-end corridors, 'murder-holes' for pouring boiling pitch over the attackers, moats, drawbridges and various other forms of death traps to surprise trespassers and protect the nobles against peasant uprisings. The lower part of the castle's stone walls are 2.4 meters (94 inches) thick and the upper part 1.8 meters (71 inches).
Construction was started in 1499 by the Danish knight Jens Holgersen Ulfstand and stone-cutter-mason and architect Adam van Düren, a North German master who also worked on Lund Cathedral. Construction was completed in 1506.
Ulfstand was a councillor, nobleman and admiral serving under John I of Denmark and many objects have been uncovered during archeological excavations that demonstrate the extravagant lifestyle of the knight's family at Glimmingehus up until Ulfstand's death in 1523. Some of the most expensive objects for sale in Europe during this period, such as Venetian glass, painted glass from the Rhine district and Spanish ceramics have been found here. Evidence of the family's wealth can also be seen inside the stone fortress, where everyday comforts for the knight's family included hot air channels in the walls and bench seats in the window recesses. Although considered comfortable for its period, it has also been argued that Glimmingehus was an expression of "Knighthood nostalgia" and not considered opulent or progressive enough even to the knight's contemporaries and especially not to later generations of the Scanian nobility. Glimmingehus is thought to have served as a residential castle for only a few generations before being transformed into a storage facility for grain.
An order from Charles XI to the administrators of the Swedish dominion of Scania in 1676 to demolish the castle, in order to ensure that it would not fall into the hands of the Danish king during the Scanian War, could not be executed. A first attempt, in which 20 Scanian farmers were ordered to assist, proved unsuccessful. An additional force of 130 men were sent to Glimmingehus to execute the order in a second attempt. However, before they could carry out the order, a Danish-Dutch naval division arrived in Ystad, and the Swedes had to abandon the demolition attempts. Throughout the 18th century the castle was used as deposit for agricultural produce and in 1924 it was donated to the Swedish state. Today it is administered by the Swedish National Heritage Board.
On site there is a museum, medieval kitchen, shop and restaurant and coffee house. During summer time there are several guided tours daily. In local folklore, the castle is described as haunted by multiple ghosts and the tradition of storytelling inspired by the castle is continued in the summer events at the castle called "Strange stories and terrifying tales".
