科隆大教堂是在130年前建成的，其中25年来，滑冰运动员在南面前牢牢占据了隆卡普拉兹的地盘。在此期间，形成了一种独立的文化，对许多人来说，广场成了他们所认同的地区。

Cologne Cathedral was completed 130 years ago and for 25 of those years skaters have firmly taken possession of Roncalliplatz in front of the southern facade. During this time, a separate culture was formed and for many, the square became an area that they identified with.

然而，近年来，人们越来越多地认为这是一个问题。一些既定的利益集团施加了压力，一些人认为应该干脆禁止滑冰。这座城市充满善意，希望与滑冰者合作解决冲突。滑冰者之间没有任何接触点，因此，他们不得不让步，使得在大教堂周围溜冰变得困难。

However, in recent years the scene has been increasingly viewed as a problem. Established interest groups exerted pressure, and some were of the opinion that skating should simply be banned. The city was full of good intentions and wanted to resolve the conflict in cooperation with the skaters. There was no point of contact among the skaters; therefore, they had to concede and made skating difficult around the cathedral.

这迫使滑冰运动员采取行动，以避免放弃他们的运动，因为没有其他类似的替代品在科隆。作为回应，他们在现场做了一些完全不寻常的事情，他们成立了一个在短时间内获得500多名成员的社会。

This forced the skaters to act to avoid giving up their sport, since there were no other comparable alternatives in Cologne. In response, they did something completely unusual for their scene; they formed a society which gained over 500 members within a short span of time.

这座城市在冲突期间有了一位联系人，他们可以与他讨论替代方案，并能代表滑冰者的利益清晰地发言，直到那时人们才能做出这样的假设。这创造了一种可能性，即能够专门为滑冰者做计划，而不是建立一个不能满足他们实际需要的标准设施。

The city now had a contact person during the conflict with whom they could discuss alternatives and who could speak clearly on behalf of the skaters’ interests, which people had only been able to assume up to that point. This created the possibility of being able to plan specifically for the skaters instead of building a standard facility that wouldn’t meet their actual needs.

基本的设计理念是通过叠加与广场相关的图像，它的用途和位置。人们流经已建成的城市景观，每个人都像河流中的水滴。滑冰运动员把这种人流变成了一场比赛。安静的，漫长的伸展，大半径与跳跃的障碍交替，就像在河流中流动和喷水一样。莱茵河上广场的位置将这幅图像置于适当的风景环境中。

The basic design concept was created by overlaying the images associated with the square, its use and its location. People flow through the built-up urban landscape, each like a water droplet in a river. The skaters have made this flow of people into a game. Quiet, long drawn-out stretches with large radiuses alternating with jumping at obstacles, like the flowing and spraying of water in a river. The location of the square on the Rhine places this image in an appropriate scenic context.

 Concept Sketch

概念草图

这一概念在现实中的实现是通过在交叉点用一个具有均匀建筑面积的虚拟网格覆盖该区域来实现的。网格和建筑区域代表城市元素，是从城市环境中剥离出来的。

The implementation of this concept in reality is achieved by overlaying the area with a virtual grid which has uniform building areas at the cross-over points. The grid and building areas represent urban elements and are taken from the urban environment.

然而，要将网格上的这种严酷的分组变成一种适合这项运动的自发安排，就必须使用一种特定的算法对该区域进行重组。这使得建筑区域变成了不同大小的建筑；它们从景观中爬出来，或沉入其中，在空间中散布着绿色元素、草地和树木。最基本的结构是用混凝土制成的溜冰鞋，在石板河中，像被水覆盖的石头一样站立。

However, to turn this stark grouping on a grid into a spontaneous arrangement that is optimal for this sport, the area had to be reorganized using a particular algorithm. This turned the building areas into structures of different sizes; they rise out of the landscape or sink into it to intersperse the space with green elements, meadows and trees. The basic structures are skate objects made from concrete and stand like stones covered by water in a river of flagstones.

Realization

由于它的特殊用途和它在洪水平原上的位置，广场不得不应对许多经常矛盾的挑战。小型硬质滑板轮需要尽可能平整光滑的表面，以避免跌倒时的放牧，同时确保公共广场在下雨时的防滑质量。

Due to its special use and its location on the flood plain, the square has to cope with many often contradictory challenges. The small hard skateboard wheels require a surface that is as level and smooth as possible to avoid grazing in the event of falls while ensuring the non-slip quality of the public square when it rains.

这一地区的斜坡必须确保莱茵河洪水和雨水完全流走，同时不太陡峭，不宜滑冰。滑冰运动员的跳跃以及严寒的冬天和洪水不能长期影响广场的质量，这是由它的结构和材料的选择所保证的。最后，必须遵守预算和最后期限，在这两种情况下都取得了成功。

The incline of the area must ensure Rhine flood water and rain run off completely, while not being too steep for skating. Skaters’ jumps as well as hard winters and flooding must not affect the quality of the square over the long term, which is ensured by its construction and the selection of materials. Finally, the budgets and deadline had to be observed, which were successful in both cases.
