The Heidenmauer ('heathen wall') is a circular rampart or ringwork, two and a half kilometres long, which was built by the Celts around 500 BC. The wooden elements of the wall have disappeared over the course of time by rotting away, but the stones have survived. Copious numbers of pottery finds have enabled a very precise dating. Almost all the containers are hand-made, only a few show traces of having been turned; this technology first appeared after ch 500 BC. in the La Tène period. Other finds included iron, long knives as well as querns, pyramidal stones that were stuck point-down in the ground in order to provide the base for the milling of corn. In addition there is also evidence of milk production and iron smelting.
In the 4th century A. D. a small part of the circular rampart as well as the Kriemhildenstuhl below was used by the Romans as a quarry.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.
