La Chaux-de-Fonds / Le Locle — Watchmaking Town Planning
Two Swiss Jura towns rebuilt from scratch after fires, their street grids deliberately oriented to maximise daylight for watchmakers — a unique form of urban planning that turned the entire city into a workshop. UNESCO World Heritage Site since 2009, and the birthplace of Le Corbusier.
At a glance
La Chaux-de-Fonds (population c. 40,000) and Le Locle (c. 10,000) are two adjacent towns in the Swiss Jura mountains, inscribed on the UNESCO World Heritage List in 2009 as the most complete example of planned watchmaking urban environments in the world. Both were rebuilt after devastating fires — La Chaux-de-Fonds in 1794, Le Locle in 1833 — as purpose-designed cities where the street layout, plot sizes, and building orientation were all calculated to provide maximum north-south light for the delicate hand-work of watchmaking. The towns remain active watchmaking centres and are together home to major watch brands including Tissot and Zenith.

History and context
The Swiss Jura watchmaking tradition developed in the seventeenth and eighteenth centuries as a cottage industry. In the Jura valleys, winter was too long and the terrain too rugged for farming alone, and the precision skills demanded by watchmaking — learned in workshops, passed from father to son — created a dense network of home-based production. Watch components were assembled at home, passed to neighbours, gathered by merchants, and assembled into finished watches. The supply chain lived within walking distance.
When fire destroyed La Chaux-de-Fonds in 1794, the town was rebuilt to a plan drawn up specifically to support watchmaking. The new street grid was set on strict parallel lines running east-west, with long narrow plots on each street that allowed every workshop-house to receive maximum north-facing light throughout the day. The same logic was applied to Le Locle after its 1833 fire. This made both towns unique in urban history: cities planned not for defence, commerce, or prestige, but for a specific manufacturing process.
La Chaux-de-Fonds is also notable as the birthplace of Le Corbusier, born Charles-Edouard Jeanneret in 1887. He trained as a watch-case engraver here — the Jura tradition of precision surface work almost certainly influenced his later obsession with proportion, surface, and the Modulor. Several of his early houses survive in the town, including the Villa Fallet (1905) and the Villa Jeanneret (1912).
What you see
The most striking feature of both towns is the grid itself: standing on any street in La Chaux-de-Fonds, you can see the long parallel blocks stretching away toward the horizon, each front facade aligned to catch the same quality of north light. The streets are wide and straight, built not for grandeur but for practicality — to allow delivery carts and daylight to reach every door.
The buildings themselves are a dense mixture of residential and commercial, with workshops integrated into houses on the upper floors or in the back courtyards. Many buildings retain the large windows of the watchmaking era — wide openings designed to let diffuse northern daylight flood the workbench. The International Watchmaking Museum (MIH) in La Chaux-de-Fonds provides context and history, with a collection tracing the development of precision timekeeping from the earliest clocks.
Le Corbusier’s early works, including the Villa Schwob (1916) and the Villa Jeanneret-Perret (1912), show the young architect experimenting with the same clarity, light, and proportion that would later define his mature style — all formed against this background of Jura precision.

Getting there
La Chaux-de-Fonds is connected to Neuchatel by direct train (30 minutes) and to Bern via Le Locle. The SBB Swiss rail network serves both towns. By car, the A20 motorway connects to La Chaux-de-Fonds from the Swiss Plateau; the mountain road offers spectacular views of the Jura. The altitude (1,000 m) means the town can be snowbound in winter — check conditions before driving.
