在科西嘉岛东北海岸的第二大城市Bastia, Dietmar Feichtinger建筑事务所与当地建筑师Buzzo Spinelli、Insitu景观设计事务所和Sbp的工程师合作，设计了Aldilonda滨海步道。在科西嘉当地俗语中，“Aldilonda”代表“海上”。

In Bastia, Corsica’s second largest city on the north-east coast, Dietmar Feichtinger Architectes achieved the promenade Aldilonda, which means “Above the Sea” in Corsican with local architects Buzzo Spinelli, Insitu landscape and the engineers of Sbp;

Aldilonda步道坐落于海岸线的悬崖峭壁之上，距海平面约有5米的距离。这些岩石构成了巴斯提亚堡垒坚固围墙的巨大天然地基，这座城市也因此而得名。到目前为止，人们只能通过城墙到达部分海岸线沿岸。

Anchored in the rock, Aldilonda follows the cliffy coastline five meters above sea level. The rock forms the massive natural foundation of the mighty enclosing wall of Bastia’s fortress, which gave the city its name. Until now, the coastline under the fortress wall was only partially accessible.

本项目不仅仅为人们提供了沿海步道，同时也成为观赏海景的全新景点。细长的步道悬于海天之间，与大自然一起组成一幅壮丽的景观画面。柔和弯曲的道路与巨大的堡垒以及城堡下的岩石形成鲜明的对比。步道时而紧贴岩壁，时而悬于磐石之上，时而穿过山体，巧妙地融于岩石之中，小心翼翼地穿越海岸丰富的自然空间。红色的步道围栏由耐候钢制成，在大浪来袭时保证了人们的安全。金属栏杆疏密有度，在保证安全的前提下，避免了对观景视野造成的影响，而锈红的色调则与含铁的岩石相互协调。

More than a path, a destination with new perspectives on the open sea, suspended between sea and sky, Aldilonda becomes a spectacular event. The softly curved path contrasts the massive fortress and the rock on which the bastion is founded. The path nestles against the rock, leans against it, and breaks through it. Sensitively, the construction blends into the rock, the rich natural space of the coast is carefully traversed. At the same time, the red band of the railing made of Corten steel offers a high sense of security above the surf. The bars offer maximum transparency, the iron-bearing rock harmonizes with the rusty red of the railing.

步道变宽的部分为人们提供了休憩的空间；紧贴岩壁的部分采用了不锈钢网格作为地面，透过网格便可以看到下方的大海；混凝土路面部分则悬于岩石之上，暴露在汹涌的海浪之中；当大浪来袭时，海水穿过不锈钢网格，从而减小了巨浪对步道的冲击，保证了结构的稳定。此外，设计团队还在La-Seyne-sur-Mer的盆地模拟出每平方米14吨冲击力的海浪，对步道的建筑结构进行了抗冲击力测试。此外，为了确保材料的耐用性，设计中还采取了特别的保护措施，例如，在步道最暴露于海浪之中的部分进行了加固，使材料密度达到400kg /m3左右。由于步道结构部分悬空，因此施工技术较为复杂，需要将工人们悬吊在城堡的平台上进行施工作业。此外，在施工时还需要设置钻床来固定25米长的拉力杆。

The path widens out and offers places to rest. The sea can be experienced through the area covered with a transparent grid. The balcony is exposed to the rough surf; when the waves are high, the water penetrates the stainless-steel grid on the rock, thus reducing the massive force of the water. Hydraulic tests in a basin in La-Seyne-sur-Mer were necessary to determine the force of the wave impact at 14 tons per square meter. Special care was also taken to ensure the durability of the materials. For example, the reinforcement density in the areas most exposed is around 400 kg/m3. The acrobatic use of workers, suspended from the platform of the fort on the trapeze, made it possible to anchor the construction in the rock. Drilling jigs had to be designed to anchor the 25-metre-long tension bars.

堡垒南端保持不变

The southern point of the fortress remains untouched

为了使堡垒围墙的南端，也就是城堡延伸至海里的部分，保持原样；步道南端的小径采取了长廊与隧道的形式。隧道穿过岩体，在出口处形成缓坡，将海上人行道与“ Spacimare”长廊连接起来。垂直采光井为隧道提供了自然光线，与隧道相连的楼梯则通向城堡上部的观景平台。通道侧墙和天花板由清水混凝土制成，灯光嵌在天花板上。混凝土材料表面保留了模板的木质纹理，在光线的照射下形成细腻的光影效果。

To keep the toe of the fortification wall, which stretches furthest into the sea, clear, the path at the south end pierces the rock in the form of a gallery, a tunnel. It connects the walkway above the sea with the “Spacimare” promenade by a gently sloping path at the exit of the tunnel. A vertical light well provides natural light to the passage. A staircase leads up to the elevated plateau of the fortress. The side walls and the ceiling are made of fair-faced concrete. The wood grain of the shuttering is reflected on the surface. The lighting is embedded in the ceiling.

无障碍通道

One access for all

步道的北端连接到楼梯，可直接通往旧港口。 同时，缓缓倾斜的坡道位于“Jetéedu Dragon”码头墙的一侧，坡道两侧的围栏封住了原码头楼梯的入口。老年人、坐轮椅的人、推婴儿车的父母、骑自行车或是滑旱冰的人可以由海边步道到达码头。

To the north, the path connects to a staircase that provides direct access to the old harbor. At the same time, a gently sloping ramp accompanies the quay wall “Jetée du Dragon” and closes off the promenade accessible to all, elderly people, people in wheelchairs and parents with children in prams, as well as cyclists and rollerblades.

红色飘带

The red ribbon

步道围栏由间距为110mm的耐候钢细柱构成，坚固耐用。铁锈红色的栏杆与富含铁的岩石相互呼应、色彩协调。混凝土路面的外侧包裹着L形耐候钢材起到保护结构的作用。围栏的立柱直接焊接在L形耐候钢上，立柱的排布遵循了路径的起伏动态。 因此，从正面看，围栏呈现出最高的透明度，而从侧面看，则形成一条连续紧密的飘带，为人们提供了极高的心理安全感。

The safety is formed by narrowing uprights with a spacing of 110mm. These are made of solid Corten steel. The iron-rich rock harmonizes strongly with the rust red of the railing. An L-shaped profile, also made of Corten, closes off the concrete on the outside of the path. The individual uprights are welded to the L-profile and follow the undulation of the path. Frontally they offer maximum transparency. From the side, they form a band that provides a sense of safety.

精心设计的照明

The discreet lighting

围栏上，每隔三米就设有一组LED照明灯带，这些灯带与栏杆巧妙地融为一体，小心翼翼地照亮了小径与人行道下方的岩石，营造出梦幻的光影氛围。

At intervals of three meters, LED strips are integrated into the uprights as lighting. They discreetly illuminate the path and the rock in the lower area of the walkway.
