Mesocco Castle ruins are among the largest in the canton. Originally the seat of the noble family von Sax, from the 12th century until 1480 it was held by the Freiherr of Misox/Mesocco. From 1480 until 1549 it was held by the Trivulzio family.
A small fortified church, the Church of S. Carpoforo, was built on the hill top around the 7th century as a refuge castle for the surrounding villages. Around 1000, the fortifications around the church began gradually expanding and a bell tower was added to the church. A bergfried was added between 1150 and 1200, changing the shape and location of the walls. By the 12th century the fortified church and occasionally used fortifications had expanded into a permanently occupied castle with a nobleman who ruled over the nearby valley. By 1219 it was mentioned as Mesocco Castle. In the 13th century the castle was expanded again. A ring wall now encircled the entire hill top and a large residential wing was added to the tower. Around 1400 the residential wing was expanded and now formed an inner castle with the tower.
The first ruler of the castle was the local Baron of Sax/Misox, who by the 13th century ruled over the entire Val Mesolcina and controlled a number of castles. By the end of the century, the baron's power crossed over the San Bernardino Pass and by the 14th century they reached the peak of their power. Baron Albert von Sax-Misox was a founding member of the Grey League and the family's future looked bright. However, Albert's murder in 1406 led to the gradual decline of the family. In 1480 they sold Mesocco castle and its associated demesne to General Giacomo Trivulzio.
Trivulzio had been sent by Milan to acquire the castle and strengthen their claims in the strategic valley. After he paid a deposit on the castle and occupied it, he refused the pay the remainder of the agreed upon price of 16,000 Rheingulden. In 1483 the Baron of Sax and local forces besieged the castle in an unsuccessful attempt to force Trivulzio to pay. However, over the following years, he broke with Milan and paid the remaining money to improve local relations. In 1490 Trivulzio expanded and strengthened the castle and sited cannons on the walls.
In 1496 he signed a treaty with the Grey League to support them with weapons and supplies in the event of a war, which he was called to do during the Swabian War and Musso War. Despite the extensive fortifications, in 1526 the newly formed Three Leagues ordered the castle abandoned and moved the administrative center of the valley to Palast Trivulzio in Roveredo.
The castle fell into ruin until 1925-26 when it was excavated and reinforced. A further project in 1986-90 restored a polygonal tower and northern and north-western walls.
The castle sprawls over the entire top of a small mountain. The walls form an irregular pentagon with five towers. The interior of the castle was home to the count's family and his soldiers as well as armories, a foundry, a bakery, a dairy, a cistern and a charnel house. The church of S. Carpoforo also stood inside the castle walls. At the foot of the castle is the Church of Santa Maria al Castello. The church was first mentioned in 1219. It houses several frescoes from the workshop of Seregnesi from the mid-15th century.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".
