随着向公众开放它的决定，有必要建造一座建筑物来支持游客，但它也将保护洞口的天窗。该建筑项目试图同时实现这两个目标，通过一个起伏的石墙，转化为一个复杂的花边在与建筑物的接触点。这提供了一个光的入口是过滤和连续的，允许均匀照明的内部，并避免了其他开口的必要性。

With the decision to open it to the public it became necessary to construct a building to support visitors, but one which would also protect the skylight of the entrance to the cave. The architectural project sought to simultaneously achieve both aims by means of an undulating stone wall which transformed into an intricate lacework at the point of contact with the building. This provides an entrance of light which is both filtered and continuous, permitting the uniform illumination of the interior and avoiding the necessity for other openings.

除了这堵墙外，该建筑还涂上了一层不透水的黑色饰面，以补充洞穴内玻璃化熔岩的颜色和质地。

With the exception of this wall the building is coated with an impermeable black finish in order to complement the colour and texture of the vitrified lava within the cave.

在如此强烈的景观面前，我们的目标是将建筑，尽管其当代设计，与其周围的规模、性质和环境相结合。

In the presence of so strong a landscape our aim was to integrate the building, notwithstanding its contemporary design, within the scale, nature and context of its surroundings.
