The Fraeylemaborg was one of the most important borg in the province of Groningen. These strong houses or keeps were built in the Middle Ages to store harvests and to protect their produce from robbers. Besides churches, these structures were the only buildings that used durable stone and masonry. In due time they grew to become centres of power and wealth. The Fraeylemaborg is located in the middle of the town of Slochteren which upon its discovery in 1959 gave its name to the largest gasfield in the world.
In 1475 there was already a farm with the name Frealemaheerd. The building originates from the 16th century. The left wing was built in the 17th century. In 1680 the borg was sold by Evert Rengers, son of the former lord of the manor, because of his family debts. It was bought by Henric Piccardt (married to Anna Elizabeth Rengers, Evert's sister), who borrowed the necessary funds from Stadtholder William III. Piccardt extensively rebuilt the borg and he also landscaped a huge formal garden in the style of Louis XIV's France. After Piccardt's death the borg fell into disrepair. In 1781 the Fraeylemaborg was sold to Hendrik de Sandra Veldman. He rebuilt it into the shape it has today. Among his innovations was the removal of two towers which had graced the front square.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.
