格拉芬内格云塔丨奥地利

格拉芬内格城堡园区可被视为一座占地31公顷的树木园。该公园深受游客喜爱，如今以云塔这一全新的亮点与制高点进一步丰富其景观层次。然而，这座露天舞台并未试图与园中树龄可达150年的高大乔木竞争，相反，在某种程度上，它自身也成为其中的一部分。尽管其结构由混凝土与钢材构成，云塔的轮廓却融入了景观花园之中，成为既有场景叙事中的一次当代介入。

Grafenegg Castle Grounds can be interpreted as a 31-hectare arboretum. The park is a much-loved visitor destination, which has a new highlight – and high point – in the shape of the Wolkenturm. However, rather than seeking to compete with the huge trees, which are up to 150 years old, the acoustically acclaimed open-air stage becomes, to a certain extent, one of these itself. Notwithstanding its concrete and steel construction, the outline of the Wolkenturm merges into the landscape garden, a contemporary intervention in an existing scenography.

云塔被编织进园内的路径网络之中，随着观众或游人在公园中漫步并从不同方向接近，其形态不断发生变化。这些路径经过精心布置，使得不断变化的空间场景如同一部电影般展开。塔体本身的高度与古树相呼应，并扎根于场地既有的地形凹陷之中；而舞台、可容纳1700人的观众席同样嵌入原有地形，与布置在起伏草地中的座席共同营造出一个全新的场所，并自觉地与自然环境建立起共生对话。

Woven into the network of paths, the Wolkenturm changes shape, depending upon the direction from which it is approached by concertgoers and others, who are strolling through the park. These paths are consciously positioned to ensure that the constantly changing scenario unfolds like a film. The tower itself adopts the height of the ancient trees. It puts down its roots in an existing hollow in the ground, while the stage, the 1,700-seat auditorium, which also nestles into the existing topography, and the areas of seating on the lawns set into the gently rolling landscape create a completely new place that knowingly establishes a symbiotic dialogue with its natural surroundings.

位于轻盈雕塑般云塔之下的舞台区域亦可被视为一件乐器，它对声音进行捕捉与汇聚，并将其传递给听众。为优化观演视线与声学效果，观众与表演者之间的距离被尽可能缩短，从而赋予场地一种宜人的亲密感。宽敞的后台空间以及在需要时可灵活使用的舞台，也使其能够承载多种类型的活动。

The area of the stage below the airily sculptural Wolkenturm is also to be understood as an instrument. It captures and concentrates the sound before passing this on to the listeners. In order to optimise both the view and the acoustics, the audience is very close to the performers, which lends the location an agreeable sense of intimacy. The generous backstage area and, if required, the stage itself can also be used for many other sorts of event.
