Luxembourg - Vianden - Le Château

Vianden - Le Château (Vianden Castle).

Sent by Christina, a postcrosser from Germany.

This is from Wikipedia : Vianden Castle (French: Château de Vianden, German: Burg Vianden Luxembourgish: Buerg Veianen), located in Vianden in the north of Luxembourg, is one of the largest and most beautiful fortified castles west of the Rhine. With origins dating from the 10th century, the castle was built in the Romanesque style from the 11th to 14th centuries. Gothic transformations and trimmings were added at the end of this period. A Renaissance mansion was added in the 17th century but thereafter the castle was allowed to fall into ruin. It has, however, recently been fully restored and is open to visitors.

Set on a rocky promontory, the castle stands at a height of 310 metres, dominating the town of Vianden and overlooking the River Our about a hundred metres below. The castle and its dependent buildings have a total length of 90 metres.

The castle was built on the site of an ancient Roman castellum. The basement appears to have been a Carolingian refuge. Historically, the first Count of Vianden was mentioned in 1090. The castle continued to be the seat of the Vianden's influential counts until the beginning of the 15th century.

Around 1100, a square keep was built as well as a kitchen, a chapel and residential rooms indicating that an aristocratic family lived there at the time. During the first half of the 12th century, a new residential tower and a prestigious decagonal chapel were added while the palace itself was extended. At the beginning of the 13th century, a new two-storey palace measuring 10 by 13 metres was built with a sumptuous gallery connecting it to the chapel. These additions show how the Counts of Vianden sought to rival the House of Luxembourg. The last great change took place in the middle of the 13th century when the entire castle was adapted to reflect the Gothic style. Finally, in 1621 the Nassau Mansion with its banqueting hall and bedroom was built by Prince Maurice of Orange-Nassau-Vianden in the Renaissance style replacing a damaged side wing of the 11th century keep.

During the 16th century, the castle was more or less abandoned by the Counts of Vianden who had gained the additional title of the House of Nassau-Orange after Elisabeth, the grand-daughter of Henry II of Vianden had willed the County of Vianden together with its castle to her cousin, Count Engelbert of Nassau. This initiated the long association between Vianden and the House of Nassau. In 1564, William the Silent, Prince of Orange, Count of Nassau and of Vianden, took an initial interest in Vianden where he built the first blast furnace in Luxembourg but left in 1566 to lead the Dutch revolt again the King Philip II of Spain. As a result, Philip confiscated the castle and conferred it on Peter Ernst von Mansfeld, the governor of Luxembourg.

In 1820, King William I sold the castle to Wenzel Coster, an alderman, for 3,200 florins. Coster started to demolish the building, selling off the tiles from the roof, the wooden panelling, the doors and the windows piece by piece. Soon the castle was a ruin.

This is from Wikipedia : Luxembourg (pronounced LUKS-əm-berg), officially the Grand Duchy of Luxembourg (Luxembourgish: Groussherzogtum Lëtzebuerg, French: Grand-Duché de Luxembourg, German: Großherzogtum Luxemburg), is a landlocked country in western Europe, bordered by Belgium, France, and Germany. Luxembourg has a population of over half a million people in an area of approximately 2,586 square kilometres (999 sq mi).

Luxembourg is a parliamentary representative democracy with a constitutional monarch; it is ruled by a Grand Duke. It is the world's only remaining sovereign Grand Duchy. The country has a highly developed economy, with the highest Gross Domestic Product per capita in the world as per IMF and WB. Its historic and strategic importance dates back to its founding as a Roman era fortress site and Frankish count's castle site in the Early Middle Ages. It was an important bastion along the Spanish Road when Spain was the principal European power influencing the whole western hemisphere and beyond in the 16th–17th centuries.

Luxembourg is a founding member of the European Union, NATO, OECD, the United Nations, Benelux, and the Western European Union, reflecting the political consensus in favour of economic, political, and military integration. The city of Luxembourg, the capital and largest city, is the seat of several institutions and agencies of the European Union.

Luxembourg lies on the cultural divide between Romance Europe and Germanic Europe, borrowing customs from each of the distinct traditions. Luxembourg is a trilingual country; German, French and Luxembourgish are official languages. Although a secular state, Luxembourg is predominantly Roman Catholic.
