The history of Arosa as a permanent settlement began relatively late compared to other regions in Switzerland. For a long time, these high-altitude lands were used exclusively as summer pastures for livestock by residents of the lower part of the valley.
The situation changed after 1300, when free Walser peasants from Davos arrived in these territories. The first documented mention of the settlement under the name Araus dates back to 1330. Linguists believe the name itself has older, possibly pre-Roman roots.
Key Factors of Development
Walser Migration: This was the main catalyst for development. The settlers brought with them the German language, displacing Rhaeto-Romanic dialects, and their traditions of building wooden houses adapted to the harsh climate.
Geographical Isolation: Being located at the end of the Schanfigg Valley at an altitude of about 1,700–1,800 meters provided natural protection but also made trade difficult. For a long time, contact with the outside world was maintained only through narrow mountain paths.
Early Cultural and Economic Features
Until the appearance of the first tourists at the end of the 19th century, Arosa remained a modest mountain village. The life of the local population was determined by two main factors:
Subsistence Farming: The basis for survival was high-altitude cattle breeding and the production of dairy products. Harsh winters dictated a special, ascetic way of life.
Ore Mining: An interesting historical fact is the development of mining. In the 14th and 15th centuries, iron ore was mined in the vicinity of Arosa, which temporarily brought income to the community until the reserves were exhausted.

Milestones
Stages of Resort Transformation
The development of Arosa is a story of a remote mountain village transforming into a world-class resort. Key events that shaped the town's modern appearance are linked to overcoming geographical isolation and a flexible shift in economic models.
Breaking Transport Isolation (1890): The completion of the Schanfiggerstrasse road was a turning point in urban development. Before this, goods were delivered by mules, making large-scale construction impossible. The road allowed materials to be brought in for the first stone grand hotels, initiating the architectural reconstruction of the settlement.
The Era of Climatic Treatment (Late 19th Century): Thanks to the initiative of Dr. Otto Herwig, Arosa gained the status of an elite health resort for lung patients. This triggered the first economic boom: the service and medical sectors became the foundation of prosperity, virtually displacing traditional agriculture.
Railway Revolution (1914): The launch of the Chur-Arosa line of the Rhaetian Railway provided comfortable and stable access to the resort in any weather. This event opened the town to mass tourism and a wealthy international public, finally integrating Arosa into the European transport network.
Reorientation toward Sports (Mid-20th Century): As medicine advanced, the demand for climatic sanatoriums fell. The town successfully repositioned itself as a winter sports center. The construction of the first ski lifts radically changed the use of the surrounding landscape, turning slopes into an economic asset.
Conquering the Heights (1957): The opening of the cable car to the summit of the Weisshorn (2,653 m) was a major milestone. This not only expanded the skiing area but also made panoramic views accessible to hikers, creating a new center of attraction.
Strategic Merger (2013–2014): The construction of the Urdenbahn aerial tramway connected Arosa with the neighboring resort of Lenzerheide. This urban and economic decision created one of the largest ski areas in Switzerland (225 km of slopes), significantly increasing the region's competitiveness on the global market.
Architecture
From Walser Village to Alpine Modernism
The architectural character of Arosa is a fascinating dialogue between centuries-old traditions and bold contemporary solutions. Unlike towns with a single historical center, Arosa developed as a "dispersed settlement" (Streusiedlung), which allowed buildings from many different eras to be seamlessly integrated into the mountain landscape.
Traditional Architecture: Walser Heritage (15th–19th Centuries)
The earliest architectural layer of the town is represented by the buildings of the Walser settlers. This is a rugged yet picturesque style, dictated by the climate and available materials.
Style: Vernacular wooden architecture (log construction). Houses were built from massive logs that darkened in the sun over time to a blackish-brown color. Small windows were typical to retain heat, and roofs were covered with wooden shingles or stone.
Landmark Building:Mountain Chapel (Bergkirchli). Built in 1493, it is the resort's oldest building. The modest stone structure with a wooden tower combines the simplicity of rural architecture with Late Gothic elements (the vaulted ceiling of the choir).
The Belle Époque and Sanatorium Style (1880–1940)
Arosa's transformation into an elite health resort radically changed its urban planning. Stone replaced wood, and modest huts gave way to impressive volumes.
Grand Hotels (Historicism): In the late 19th century, the first large hotels appeared (such as the Kulm Hotel), imitating the palatial architecture of lowland Europe. Here, you can find elements of Neoclassicism and the Swiss "chalet" style on an enlarged scale.
Sanatorium Modernism (Neues Bauen): In the 1920s and 30s, architecture became functional. The treatment of tuberculosis required plenty of sun and fresh air. This led to buildings with flat roofs, clean lines, and huge south-facing terrace balconies. This style, known as "New Building" (Neues Bauen), gave Arosa the features of a modern city earlier than many other Alpine villages.
Contemporary Architecture: High-Tech and Sustainability
In the 21st century, Arosa has become a platform for ambitious projects by world-renowned architects who seek to integrate buildings into the surrounding nature rather than dominate it.
Tschuggen Bergoase: The town's most famous modern landmark, designed by the renowned architect Mario Botta. The spa complex is built directly into the mountain, with only expressive glass "sails" (skylights) visible on the surface, which light up at night to create a futuristic landscape.
Valsana Hotel: An example of modern eco-architecture. The building, with its wood and stone facade, looks traditional but hides advanced energy-efficiency technologies inside, including the use of geothermal energy and "ice batteries."
Kursaal Renovation: The historic casino and entertainment center building was modernized, preserving its cultural status while receiving a modern "interior" for hosting events.
