The Palais des Nations

The Palais des Nations stands in the 55-acre Ariana Park known for its beautiful trees, many of which were planted when the property belonged to the Geneva family of Revilliod de la Rive. It was Gustave Revilliod who bequeathed the park to the City of Geneva in 1890.

The Armillary Sphere is situated in the Court of Honour of the Palais des Nations, facing the Assembly building. It was presented to the League of Nations in 1939 by a private American society, the Woodrow Wilson Foundation, in memory of President Wilson, founder of the League. The bronze sphere represents the signs of the zodiac. It was designed by the American sculptor Paul Manship and was cast and finished in Italy by Bruno Bearzi. The sphere rotates in the same direction as the earth and is inclined at the same angle.

Semmering-Bahn

The Semmering Railway, built over 41 km of high mountains between 1848 and 1854, is one of the greatest feats of civil engineering of this pioneering phase of railway building. The quality of its tunnels, viaducts and other works has ensured the continuous use of the line up to the present day. It runs past a background of a spectacular mountain landscape containing many fine recreational buildings resulting from the opening up of the area with the advent of the railway. With the construction of the Semmering Railway, areas of great natural beauty became more easily accessible, and as a result these were developed for residential and recreational use, creating a new form of cultural landscape.
 

Pferdeschwemme, Salzburg

The Pferdeschwemme, or horse-pond, situated on Herbert-von-Karajan-Platz in Salzburg, was planned and built by Fischer von Erlach around 1695. Here the horses of the archbishop's stables could drink and were washed. The horse frescoes are by court painter Franz Anton Ebner, the middle group showing a fresco of a horse trader by M. B. Mandl. The frescoes serve as an encasement of the former quarry. The magnificent Schwemme underlines the significance of horses in the baroque period. Behind the Pferdeschwemme is the Sigmundstor Sigmund's Gate), which was created in the eighteenth century to join the old quarter and the quarter called Riedenburg.
 

Ruine Aggstein an der Donau

The Aggstein ruin, beautifully situated on top of a rock 300 m above the Danube valley, was first documented as a stone castle built during the first quarter of the twelfth century. In 1181, the castle became the property of the Kuenringer, landed gentry of medieval times who colonized large parts of the Waldviertel region north of the Danube. In 1230 and 1295, the castle was attacked and conquered by adversaries. It progressively deteriorated, and efforts to reconstruct it were finished in 1436. After that it went through several transformations. In 1529, the Turks converted it into an artillery defence, and in 1606 it was renovated in Renaissance style. When it came into the possession of Count R?iger von Starhemberg in 1685, Aggstein deteriorated. Stones and wooden beams were removed from the walls to build the Monastery of Langegg. Today only stone walls and Gothic remnants remain of this historic structure.
 

Hallstatt

The Hallstatt region comprises a multifaceted natural landscape that includes both historic and cultural dimensions. With its unique network of caves and variety of flora and fauna, the region is considered a complex phenomenon. Human activity in the magnificent natural landscape of the Salzkammergut region began in prehistoric times, when its deposits of salt began to be exploited as early as the second millennium B.C. This resource formed the basis of the prosperity of the area up to the middle of the twentieth century, a prosperity that is reflected in the fine architecture of the town of Hallstatt.
 

Stift Melk an der Donau

The Stift Melk (Melk Abbey) has been a great cultural and spiritual centre for more than 1,000 years. It was first a Babenberger castle, and then in 1089 it was transformed into a Benedictine monastery by Margrave Leopold II. For over 900 years, monks have lived there in observance of the rules formulated by Saint Benedict. Throughout its history, the convent of Melk has contributed significantly to the arts, music and natural sciences. Connected to the monastery are a school and a library, which houses a collection of precious medieval manuscripts and famous ceiling frescoes by Paul Troger. A grandiose baroque building structure was erected between 1702 to 1736 under the then Abbot of Melk, Berthold Dietmayr, and the great Austrian architect Jakob Prandtauer. Today the abbey building is Austria's most famous example of baroque archictecture and remains an important cultural ensemble of Europe.
 

Kapitelschwemme, Salzburg

The Kapitelschwemme forms the centre of the spacious Kapitelplatz in Salzburg. It is an example of Prince Archbishop Wolf Dietrich's radical reconstruction of Salzburg by which he intended to turn medieval Salzburg into the Rome of the Renaissance popes. This fountain is picturesquely framed with willow trees and was originally used to wash horses. It was created in 1732 by Franz Anton Danreiter, by order of Archbishop Leopold Freiherr von Firmians. The Neptune sculpture with the sea horses is by Josef Anton Pfaffinger. The alcove protruding from the house at the corner of Kaigasse and Kapitelgasse was not, as one would assume, a purely decorative statement but had a tangible political function. From this viewpoint the road traffic in the government quarters could be conveniently controlled.
