麦地那被认为是伊斯兰最重要的圣城之一，Al-Masjid an-Nabawi清真寺便坐落于此，其中设有先知穆罕默德的坟墓。每年，上百万朝圣者会随着伟大的朝圣之旅Hajj来到这里共同祈祷。由于拜访圣地的朝圣者数量连年增加，清真寺需要增加自身的容量。为此，人们决定在清真寺外扩建一处更大的广场。多年来，先知清真寺的内院使用SL Rasch设计的的伞罩遮阳，获得了了使用者的积极反馈。该项目以此为参考，在广场上覆盖轻质结构，旨在为祷告、集会和交流活动创造有遮蔽的区域，抵御沙特的高温。SL Rasch计划在清真寺前院建造250把遮阳伞，为15万平米的区域提供荫蔽，形成世界上最大的可变遮阳屋面。

Medina is considered one of the most important holy cities of Islam and is home to the mosque Al-Masjid an-Nabawi with the tomb of the Prophet Mohammed. Millions of pilgrims come to this place every year following the great pilgrimage Hajj to pray together. Due to the increasing number of worshippers who visit the holy place annually, the mosque’s capacity had to be increased. For this, a mosque extension in the form of a larger piazza was decided. Following the example of the inner courtyard of the Prophet’s Mosque, which has been shaded for several years by umbrellas from SL Rasch, and the positive feedback after their installation and commissioning, the idea was raised to also cover the piazza with lightweight structures. The intention was to provide protection from the hot Saudi temperatures and to create a sheltered area for prayers, meetings and exchanges. Therefore, SL Rasch planned and built 250 umbrellas on the forecourt of the mosque, shading an area of 150,000 m² and thus forming the largest convertible shading roof in the world.

遮阳伞创造的光影在清真寺前院形成了独特个氛围。可变结构打开时，彩色的饰带和接缝使它们看上去如同花朵一般。设计关注细节，遮阳伞无论闭合还是打开都能融入当地环境，成为清真寺外观的补充。为了和清真寺建筑保持一致，遮阳伞闭合时的包层由高品质的马赛克组成。

The play of light created by the umbrellas generates a unique atmosphere on the forecourt of the mosque. When the convertible structures unfold, they present themselves almost in a floral appearance through the colored ribbons and seams. With an eye for detail, the design of the umbrellas was developed both when closed and when open, so that they blend into the local context and complement the appearance of the mosque. In keeping with the architecture of the mosque, the cladding of the umbrellas for the closed condition was set with high-quality mosaics.
