The Castle of Segonzano was built in the 13th century on a rock spur, around 100 meters above the valley. The place where it's placed was probably the site of a prehistoric hillfort. Built by Rodolfo Scancio, on the authority of the Prince-Bishop of Trento, Federico Vanga, the castle served as an important fortified site guarding the trade route passing through the Adige Valley and across the Cantilaga bridge on the river Avisio.
The fortress became hugely important between the 14th and 15th centuries. In the 14th century it was owned by the Scancio, Rottenburg and Greifenstein families and then passed, in 1424, to the Dukes of Tyrol.
When German painter Albrecht Dürer passed here on his first journey to Venice in 1494, he was so impressed by the gloomy walls of the fortress, that he dedicated two celebrated watercolours to it. In 1971, Durer's historic visit to the site was commemorated by two porphyry pillars, at Faver and Piazzo di Segonzano, marking the locations from which he was inspired to paint the two views.References:
Hluboká Castle (Schloss Frauenberg) is considered one of the most beautiful castles in the Czech Republic. In the second half of the 13th century, a Gothic castle was built at the site. During its history, the castle was rebuilt several times. It was first expanded during the Renaissance period, then rebuilt into a Baroque castle at the order of Adam Franz von Schwarzenberg in the beginning of the 18th century. It reached its current appearance during the 19th century, when Johann Adolf II von Schwarzenberg ordered the reconstruction of the castle in the romantic style of England's Windsor Castle.
The Schwarzenbergs lived in Hluboká until the end of 1939, when the last owner (Adolph Schwarzenberg) emigrated overseas to escape from the Nazis. The Schwarzenbergs lost all of their Czech property through a special legislative Act, the Lex Schwarzenberg, in 1947.
The original royal castle of Přemysl Otakar II from the second half of the 13th century was rebuilt at the end of the 16th century by the Lords of Hradec. It received its present appearance under Count Jan Adam of Schwarzenberg. According to the English Windsor example, architects Franz Beer and F. Deworetzky built a Romantic Neo-Gothic chateau, surrounded by a 1.9 square kilometres English park here in the years 1841 to 1871. In 1940, the castle was seized from the last owner, Adolph Schwarzenberg by the Gestapo and confiscated by the government of Czechoslovakia after the end of World War II. The castle is open to public. There is a winter garden and riding-hall where the Southern Bohemian gallery exhibitions have been housed since 1956.
