Červený Kameň Castle was built in the 13th century as part of the chain of the Kingdom of Hungary’s frontier defense castles ranging from Pressburg to Žilina. Although the Fugger family built the massive fortress in the first half of the 16th century on the site of an original royal castle, its history is connected with the Pálffy noble family. This important Hungarian aristocratic family gradually altered it into a stately residence with rich stucco ornamentation and frescos in the interior.
The Pálfis inhabited the castle until 1945. The visitors can admire the famous times of the Castle and scenes from its rich history primarily during fencing festivals and falconers shows. Summer night tours of the Castle also have their special atmosphere.
Nowadays the Castle houses a museum presenting historic housing of the nobility.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
