La Chaux-de-Fonds and Le Locle, located in Switzerland, form a UNESCO World Heritage site renowned for their unique urban planning and watchmaking heritage. These towns exemplify a harmonious blend of residential and industrial spaces, designed in the 19th century to support the burgeoning watch industry. Their grid-like layouts, with wide streets and neoclassical buildings, reflect an innovative approach to town planning tailored to the needs of skilled artisans. Today, they stand as living testimonies to the region’s horological legacy and architectural ingenuity.
