In 1831 Mr. Franzen, the owner of the Salahmi Ironworks was given permission to establish a blast furnace and a bar-iron forge at Jyrkkäkoski. The early years were difficult, because Jyrkkäkoski was not at any close distance of main travel routes and sufficient labour was not available. In 1856, the ironworks was obtained by Paul Wahl & Co. as part of a larger consortium. A new Scottish-type blast furnace of English brick was erected at the site in 1874.
The ironworks produced pig and bar iron, as well as nails and cast products. In the early 1900s the Ironworks even had its own small steam boat. Many prominent cultural figures were seen at Jyrkkä, including the author Juhani Aho who courted the beautiful daughter of Brax, the manager of the works. The Jyrkkäkoski Works was in operation unti1 1919.
Finland’s National Board of Antiquities carried out conservation and reconstruction works at Jyrkkäkoski in 1996-98. The old ironworks has become an architectural attraction in North Savo. The blast furnaces now have impressive protective structures. In connection with the Scottish blast furnace is Ruukintupa, a cafeteria serving snacks. "Herrala", the manager’s residence dates from the 1830s and the log buildings in the yard area are even older.

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.
