The first defensive construction, a round tower, was built on Kalmarsund in the 12th century concurrently with the harbour. At the end of the 13th century King Magnus Ladulås had a new fortress built with a curtain wall, round corner towers and two square gatehouses surrounding the original tower. Located near the site of Kalmar's medieval harbor, it has played a crucial part in Swedish history since its initial construction as a fortified tower in the 12th century.
One of the most significant political events in Scandinavia took place at Kalmar Castle in 1397, when the Kalmar Union was formed - a union of Denmark, Norway and Sweden, organized by Queen Margaret I of Denmark. During the Swedish rebellion against Denmark in1520, the fortress was commanded by Anna Eriksdotter.
The fortress was improved during the 16th century under the direction of King Gustav I and his sons King Eric XIV and King John III, who turned the medieval fortress into a castle fit for a renaissance king. Kalmar Castle suffered heavy damage during the Kalmar War of 1611-13 and was badly damaged by a fire in 1642. Repairs were begun but from the end of the seventeenth century the castle was allowed to fall into disrepair.
In 1856, architect Fredrik Wilhelm Scholander (1816 - 1881) initiated restoration work at Kalmar Castle. His pupil Helgo Zettervall continued restoring Kalmar Castle in the 1880s. Architect Carl Möller drew up the plans and other documents. The work began in 1885 and by 1891 the castle had gained the silhouette it bears today. In 1919 professor Martin Olsson was charged with the continuing restoration of earthworks, the moat, the bridge and the drawbridge. Work continued until 1941, when the castle was once more surrounded by water. Today, it is one of Sweden's best preserved renaissance castles and is open to the public.References:
The Castle of Gruyères is one of the most famous in Switzerland. It was built between 1270 and 1282, following the typical square plan of the fortifications in Savoy. It was the property of the Counts of Gruyères until the bankruptcy of the Count Michel in 1554. His creditors the cantons of Fribourg and Bern shared his earldom. From 1555 to 1798 the castle became residence to the bailiffs and then to the prefects sent by Fribourg.
In 1849 the castle was sold to the Bovy and Balland families, who used the castle as their summer residency and restored it. The castle was then bought back by the canton of Fribourg in 1938, made into a museum and opened to the public. Since 1993, a foundation ensures the conservation as well as the highlighting of the building and the art collection.
The castle is the home of three capes of the Order of the Golden Fleece. They were part of the war booty captured by the Swiss Confederates (which included troops from Gruyères) at the Battle of Morat against Charles the Bold, Duke of Burgundy in 1476. As Charles the Bold was celebrating the anniversary of his father's death, one of the capes is a black velvet sacerdotal vestment with Philip the Good's emblem sewn into it.
A collection of landscapes by 19th century artists Jean-Baptiste-Camille Corot, Barthélemy Menn and others are on display in the castle.
