Mont-Soleil is known in Switzerland for its educational eco-tourism offerings as part of the Swiss Energy Park and . It is at the heart of the Chasseral Regional Park. The Décentrale is situated a 2 minutes walk from the Funisolaire cable railway, offering a 4 minute ride to the small town of St-Imier, with its Espace Noir autonomous culture center and

The Espace Noir is of special cultural importance for the region, since during the 19th century the anti-authoritarian or anarchist movement was particularly strong in this region. In 1872 the Fédération Jurassienne, which had strong support in Saint-Imier, organized a congress in Saint-Imier at which the Anti-authoritarian International Workingmen's Association or Anti-authoritarian International was founded.
