Tourbillon Castle was built sometime between 1290 and 1308 by the Bishop of Sion, Boniface de Challant, as his principal residence. After Boniface died in 1308, his successor Aymon II de Châtillon probably finished the castle. In 1352 the Upper Valais revolted against Bishop Guichard Tavel. Led by Peter de la Tour, in November of that year, they marched on Sion, burned the town and unsuccessfully besieged the castle. In 1373, the Prince-Bishop bought Majorie Castle and moved his residence off the rocky spire. However, Bishop Tavel was not able to enjoy his new palace for long. In 1375 he was captured and murdered by rebels led by Peter's son, Anton de la Tour, in 1375.
Tourbillon became the Prince-Bishop's summer residence and remained a visible symbol of secular and ecclesiastical power. In 1384 a group of rebels attacked Sion and captured Tourbillon and Majoria. Bishop Eduard of Savoy had to request soldiers from Count Amadeus VII of Savoy and Bern to retake his castles.
A large part of the castle was destroyed during the Raron affair in 1417 and Bishop Wilhelm V of Raron had to flee to Bern. The castle was then rebuilt in the 1440s to 1450s by Bishop Guillaume VI of Raron. As part of the reconstruction, the chapel was repaired and painted with Gothic frescoes which are still visible. It remained the administrative center of the diocese but in later centuries the military importance of the castle decreased. On 24 May 1788, a gigantic fire in Sion reduced the castle to ashes. The Bishop planned to rebuilt Tourbillon, but the revolutions sweeping through Europe ended the plans. The castle was excavated and restored in the 20th century.
The castle ruins are located on a rocky spire above the city of Sion. Reaching the site requires climbing steep stairs that wind around the hill. The castle is surrounded by a ring wall that follows the irregular top of the spire. On the west side of the complex is a pentagonal fortified building. The 15th century chapel is located in the south-east corner. The chapel's frescoes are still intact despite the fire that destroyed the castle. A slender watch tower still stands in this corner as well. The southern wall is fortified with a square gate house. The keep is rectangular and many of the interior walls still stand.References:
Kroměříž stands on the site of an earlier ford across the River Morava. The gardens and castle of Kroměříž are an exceptionally complete and well-preserved example of a European Baroque princely residence and its gardens and described as a UNESCO World Heritage Site.
The first residence on the site was founded by bishop Stanislas Thurzo in 1497. The building was in a Late Gothic style, with a modicum of Renaissance detail. During the Thirty Years' War, the castle was sacked by the Swedish army (1643).
It was not until 1664 that a bishop from the powerful Liechtenstein family charged architect Filiberto Lucchese with renovating the palace in a Baroque style. The chief monument of Lucchese's work in Kroměříž is the Pleasure Garden in front of the castle. Upon Lucchese's death in 1666, Giovanni Pietro Tencalla completed his work on the formal garden and had the palace rebuilt in a style reminiscent of the Turinese school to which he belonged.
After the castle was gutted by a major fire in March 1752, Bishop Hamilton commissioned two leading imperial artists, Franz Anton Maulbertsch and Josef Stern, arrived at the residence in order to decorate the halls of the palace with their works. In addition to their paintings, the palace still houses an art collection, generally considered the second finest in the country, which includes Titian's last mythological painting, The Flaying of Marsyas. The largest part of the collection was acquired by Bishop Karel in Cologne in 1673. The palace also contains an outstanding musical archive and a library of 33,000 volumes.
UNESCO lists the palace and garden among the World Heritage Sites. As the nomination dossier explains, 'the castle is a good but not outstanding example of a type of aristocratic or princely residence that has survived widely in Europe. The Pleasure Garden, by contrast, is a very rare and largely intact example of a Baroque garden'. Apart from the formal parterres there is also a less formal nineteenth-century English garden, which sustained damage during floods in 1997.
Interiors of the palace were extensively used by Miloš Forman as a stand-in for Vienna's Hofburg Imperial Palace during filming of Amadeus (1984), based on the life of Wolfgang Amadeus Mozart, who actually never visited Kroměříž. The main audience chamber was also used in the film Immortal Beloved (1994), in the piano concerto scene.
