在1873年,奥地利举办了一场世界博览会,旨在能够成为世界领导人和英格兰、法国平起平坐。维也纳展览的思想轨迹焦点就是圆形建筑结构,它是工程和设计的壮举,图为公平的开幕式5月1日,1873年。
在那一天,街上内环路上的豪华被寒冷的细雨打湿。超过二万维也纳市民出来看到庆祝活动,然而,大厅周围,利奥波德城,似乎还占不到一半的空间。作为仪式开始的信号,弗朗西斯·约瑟夫皇帝出现在中午。程序异常短暂,还不到30分钟,没有任何类型的正式演讲。然而,那天一个不变的特点是音乐。皇家歌剧院的管弦乐团和两个维也纳的声音合唱团俱乐部合作完成了韩德尔的三月,施特劳斯的华尔兹,和奥地利国家赞美诗。
Austria hosted a world's fair in 1873, as it aimed to present itself as a world leader and the equal of England and France. The structure that served as the focal point and ideological locus for the Vienna Exhibition was its striking Rotunda, a feat of engineering and design, which is pictured during the fair's opening ceremonies on May 1, 1873.
On that day, the streets of the Ringstrasse were wet with a cold drizzle. More than twenty thousand Viennese citizens came out to see the festivities, yet the area around the Rotunda, Leopoldstadt and Praterstern, did not seem even half full. Emperor Francis Joseph appeared at noon, signaling the beginning of the ceremonies. The program was unusually brief; it concluded in less than thirty minutes and lacked any type of formal speech. However, the one characteristic that immortalized that day was the music. The strains of the Imperial Opera's orchestra and the voices of two Viennese Glee Clubs united in performing Handel's March, the waltzes of Strauss, and the Austrian national hymn.
While the music emerged as a high point of the initial celebrations, the atmosphere in Vienna during the fair seemed rather half-hearted. For the past several years, the nation had been enjoying a period of economic growth and domestic prosperity. However, just a fortnight after these opening ceremonies, the Austrian stock market underwent a severe crash, wreaking havoc on the domestic economy. This frustrated the efforts of the Austrians to convey a strong impression to the international community. Ironically, it also seemed that while other countries experienced success in selling their national products to the fair visitors, the Austrian displays lay untouched. For these reasons, the atmosphere in Vienna during the fair was not as jubilant as had been seen at other exhibitions. However, the crash occurred after the Rotunda was built, so the budget for the construction of the Rotunda strikes one as fairly impressive. In July 1871, the original amount allocated for its building was 6,000,000 florins. However, in September of 1872, an additional 6,000,000 florins was added.
The website image is an 8 X 11 inch black and white engraving that appeared in the periodical Kunst und Kunstgeverbe auf der Werner Weltasstelling. One can note the presence of a small crowd, in their finest attire inside the building. It seems logical that this picture was sketched by an artist who had been present during the ceremony. This picture accurately shows the elaborate interior of the building, with its decorative ceiling panels and archways. This building was inspired by the style of the Italian Renaissance. One architect that is intimately associated with this genre is Andrea Palladio (1508-1580). His best known work may be the Villa Rotunda, which took its cue from the Pantheon in Rome. (Ree) Palladio's innovative design would earn the admiration and respect of many as a major architectural achievement. Having the central hall in a circular form also provides more floor area for the amount of wall surfaces, and gives a feeling of open space.
The foundation for the Vienna Rotunda was tenuous from the beginning; it rested on the moist earth that was often flooded by the annual springtime swelling of the nearby Danube River. Indeed, the solid earth only extended six feet beneath the structure; below that was the moist and unstable Danube waterbed. Miraculously, the spring of 1873 was unusually dry and water did not creep into the foundations. To counteract this softer ground, piles of cement were first laid, topped by blocks of brick covered by stone slabs, which formed the actual supports for the iron columns. These piles stood four feet above the ground, to ensure the stability of the foundation. The outside walls of the structure were composed of cement and stucco, with the lower portions in imitation stone. A circular arcade surrounded this area and led into four gardens.
The engineer for the Vienna Rotunda was J. Scott Russell, who utilized 4,000 tons of iron. Including its topmost crown which was 60 feet tall, its height reached to 284 feet. The diameter of the dome itself was 440 feet, with a circumference of 1,080 feet and peak of 284 feet. Its structure consisted of 32 pairs of columns of iron each 80 feet tall. It is estimated that these columns, which had been reinforced with iron plating, each individually bore the weight of 109 tons. These iron columns provided the only physical support for the dome. The supporting columns were connected by an iron circular girder riveted together on the site. In a display of modern technology, this ring was then raised by hydraulic lift, with the columns placed under it as it was elevated. Radial girders 200 feet long were bolted to the girder at its top and bottom. These measurements place the Vienna Rotunda as the largest of its kind. By comparison, it was 3.17 times larger than the dome of St. Paul's cathedral in London, 2.26 than that of St. Peter's in Rome, and 2.22 larger than the Crystal Palace in London.
The underside of the dome was covered with canvas which was laced though rings under each of the radial girders. This underside was then graced with drawings 21 feet across, lending a "fresco-like" appearance to the material.
Despite the mechanical perfection that this structure seemed to have attained, it was erected in an amazingly short amount of time. In September 1872, just months prior to the fair opening, the Rotunda "..wore the look of a prematurely ruined Coliseum..." (Gindriez, 23) It was only in the two weeks preceding the opening ceremony that the last layer of gravel was laid in front of the entrance. At this time scaffolding still shrouded the south and west portals. Floor finishing and the provision of chairs had yet to be addressed. It is estimated that the night of April 13, more than 15,000 workers were present in an attempt to bring the effort up to schedule. To speed construction, Austria even received by railway iron plates and pillars from Belgium and northern Germany.
The Vienna Rotunda was a grand structure that served as the heart of the exhibition. It was built on Austria's hopes of proving itself to the world, although this country still had difficult times ahead. However, the use of this impressive architecture granted a sense of elegance and nobility to the opening ceremonies.
