该阶梯的设计简单却高效。它不仅仅是一个普通的通道，更为人们拜访城市上方的历史城堡营造了浓郁的氛围。阶梯的形状强调了其特殊的位置—穿过后院到达城堡或从城堡穿过后院。

The solution was to be simple, yet effective, to provide access and set the mood for meeting the historical castle above the city. The form emphasizes its peculiar setting, reaching the castle through backyards and vice versa.

阶梯的起点很窄，阶梯上方还专门为孩童设计了小台阶。第一个台阶高度仅3mm，接下来的每一步台阶都比前一步台阶略高、略宽和略深。一路向上行走，会发现台阶越来越大，最后一步甚至达到0.8m高、1.6米深。攀爬阶梯需要耗费大量的体力。

The beginning of the stairs is very narrow with steps fit for dwarfs (the height of the first step is 3mm). Every next step is a fraction higher, wider and deeper. Reaching up, the steps are huge with the last one being 0.8m high and 1.6m deep. Climbing the stairs is a powerful physical experience.

阶梯是根据数学函数计算出来的，其示意图与山峰的横截面十分相似。经特殊设计的电脑程序规定了台阶的尺寸。该解决方案证明在最为标准的情况下可采用替代性方案。

The step formula is based on a mathematical function the diagram of which is the same as the cross-section of the hill. A specially designed computer program defined the dimensions of the steps. The solution proves that alternative approaches may be used even in the most standard conditions.
