Arbon

Ancient Roots and Roman Heritage

The history of Arbon is rooted in deep antiquity. Archaeological finds show that the first pile dwellings existed here as far back as the Stone and Bronze Ages. Today, the remains of these prehistoric settlements are part of the UNESCO World Heritage list, highlighting the uniqueness of the location.

The official beginning of the city's chronicles is considered to be the Roman period. In the 3rd century AD, the Romans built a fortified fort here named Arbor Felix ("Happy Tree"). It is under this name that the settlement is first mentioned in historical documents around 280 AD, making Arbon one of the oldest cities on the shores of Lake Constance.

Key Factors of Development

The transformation of a small settlement into a thriving city was due to a successful combination of several factors:

• Strategic Geography: The city is located on a peninsula jutting into the lake, which provided natural protection and an excellent view of the water.
• Waterways: Lake Constance served as the region's main transport artery, connecting northern and southern lands, which stimulated the development of trade links.
• Administrative Status: The legacy of Roman infrastructure and the subsequent transition of the lands under the patronage of the Bishops of Constance strengthened Arbon's political weight in the region.

Early Culture and Economy

In the early Middle Ages, Arbon became a significant spiritual center. According to tradition, Irish missionaries, including Saint Gall, stayed here, contributing to the spread of Christian culture and literacy. The castle, built on the foundations of the old Roman fortress, became the center of public life.

The economic life of the early city was centered around the lake. Fishing and shipping were the primary occupations of the inhabitants. Thanks to its convenient harbor, Arbon quickly became an important transshipment point for goods, especially salt and grain, laying the groundwork for its future commercial and industrial success.

Key Stages of the City's Transformation

Arbon's development is a journey from an ancient outpost to a modern industrial and tourist center. Below are the main transformations that defined the city's current appearance and status.

• Roman Urbanization (Arbor Felix)
  The construction of a stone castrum in the 3rd century laid the foundations of the urban layout. This transformed the coastal settlement into a strategic military and logistical hub, defining its role as a "gateway" to the region for centuries to come.
• Gaining Trade Independence
  The granting of city and market rights in the 13th century became the economic driver of the Middle Ages. Arbon transformed from a feudal estate into an independent center of commerce, specializing in the trade of flax and linen.
• The Industrial Revolution and the Saurer Era
  The founding of the Saurer family's engineering empire in the second half of the 19th century was the major economic event in the city's history. Arbon became a world-renowned center for the production of trucks and textile machinery, leading to a tenfold increase in population and a shift from an agrarian to an industrial way of life.
• Integration into the Railway Network
  The launch of the railway line along the lake in 1869 broke the region's isolation. This provided the necessary logistics for heavy industry and stimulated the first influx of tourists to the shores of Lake Constance.
• Architectural Modernization of the Early 20th Century
  The economic boom led to large-scale urban expansion. Entire quarters in the "New Building" (Neues Bauen) style appeared in the city, including factory buildings and workers' housing, which are now recognized as architectural monuments of national significance.
• Post-Industrial Revitalization (WerkZwei)
  The industrial crisis at the end of the 20th century triggered a process of reimagining urban spaces. Former Saurer factory areas were successfully transformed into modern residential complexes, parks, and cultural centers, shifting the city's economic focus toward services, technology, and tourism.

The Architectural Mosaic of Arbon

The urban landscape of Arbon is unique in its contrast: here, a compact medieval center harmoniously coexists with large-scale monuments of industrial architecture from the early 20th century. The city developed from a fortified core by the lake towards the mainland, and later, during the era of industrialization, expanded significantly along the shoreline.

Historical Styles and Iconic Buildings

Strolling through the city streets, one can trace the change of eras through the preserved architectural landmarks:

• The Middle Ages and Gothic
  The heart of the old town is Arbon Castle (Schloss Arbon). Its mighty main tower dates back to the 13th century and is a classic example of medieval fortification. The oldest elements of St. Martin's Church and the Chapel of St. Gall (Galluskapelle), with its preserved frescoes, also date back to this period.
• Renaissance and Half-Timbered Houses
  The residential buildings of the historical center (Altstadt) are rich with houses from the 16th–18th centuries. Winding streets are filled with buildings featuring Late Gothic and Renaissance elements. A special charm is added to the city by the traditional half-timbered houses (Riegelhäuser), characteristic of the Thurgau region, which showcase the skill of local craftsmen of that era.
• Baroque and Rococo
  The influence of these styles can be seen in the details of the city hall and the interiors of religious buildings. 18th-century reconstructions brought smoother lines and decorative elements to the facades of wealthy burgher houses, softening the city's austere appearance.

Industrial Modernism ("New Building")

A special place in Arbon's architecture is held by the heritage of the Saurer company. Unlike many old European cities, Arbon is proud of its factory buildings, which are recognized as architectural monuments of national importance.

Buildings constructed between the 1930s and 1950s belong to the Modernist style and the Neues Bauen (New Building) movement. They are characterized by:

• Strict functionality and geometric forms.
• The use of brick, concrete, and glass.
• Huge windows providing natural light for the workshops.

Today, these industrial giants in the Saurer WerkZwei district have been carefully reconstructed: the external facades are preserved, while the interior spaces have been adapted into modern lofts, offices, and cultural venues, creating an impressive example of postmodern urban reimagining.

Notable Figures of Arbon

The history of Arbon is inextricably linked with the names of people whose work propelled the city beyond a provincial settlement, turning it into a spiritual center in the Middle Ages and an industrial giant in the modern era.

Historical and Spiritual Leaders

• Saint Gallus — Irish missionary and educator (7th century).
  One of Switzerland's most revered saints. He spent the final years of his life in Arbon and passed away here around 640. The famous Monastery of Saint Gall later arose at his burial site, but it was Arbon that served as his final refuge, making the city an important pilgrimage center of the early Middle Ages.
• Hugo von Hohenlandenberg — Bishop of Constance (1457–1532).
  An influential ecclesiastical and political figure who chose Arbon as his residence. It was by his order in the early 16th century that the medieval fortress was rebuilt into a modern castle (Schloss Arbon), which is the city's main attraction today.

The Saurer Dynasty

A family of industrialists who shaped the city's economic destiny for a century and a half.

• Franz Saurer — Company Founder (1806–1882).
  In 1863, he moved his foundry from St. Gallen to Arbon. This step marked the starting point of the city's industrial era. Beginning with the production of household goods, he laid the foundation for the future engineering giant.
• Adolph Saurer — Industrialist (1841–1920).
  Franz's son, who transformed the family business into a world leader. Under his leadership, the factory began producing famous embroidery machines and later the first gasoline engines, providing jobs for thousands of residents in the region.
• Hippolyt Saurer — Engineer and Innovator (1878–1936).
  A representative of the third generation of the dynasty. It was he who bet on the production of trucks and buses, which made the Saurer brand famous worldwide. His technical innovations turned Arbon into one of the centers of European automotive engineering.

Culture and Modernity

• Heinrich Steinbeck — Composer and Conductor (1884–1967).
  A well-known Swiss composer who lived and worked in Arbon for many years. His marches and works for brass bands became classics of the genre, and his cultural legacy is still honored in the city's musical circles.
• Jakob Züllig — Entrepreneur and Patron (1921–1999).
  Played a key role in the city's recent history. During the crisis of the 1980s, he acquired a significant portion of the former Saurer factory real estate. Thanks to his investment and vision, the industrial ruins were not demolished but transformed into modern residential and cultural spaces, preserving the historical look of the waterfront.
