France–Switzerland border in the context of "Mulhouse"

The Jura Mountains (/ˈdʒʊərə, ˈʒʊərə/ JOOR-ə, ZHOOR-ə) are a sub-alpine mountain range, a short distance north of the Western Alps, and mainly demarcate a long part of the French–Swiss border. While the Jura range proper ("folded Jura", Faltenjura) is located in France and Switzerland, the range continues northeastwards through northern Switzerland and Germany as the Table Jura ("not folded Jura", Tafeljura), which is crossed by the High Rhine.

Diplomatic relations between France and Switzerland have traditionally been close, through important economic and cultural exchanges. Switzerland and France (which is part of the European Union), share about 600 km of border (prompting strong cross-border cooperation) and a language (French is one of Switzerland's four official languages).

French-Swiss relations date back to the Middle Ages, when the Kingdom of France and the Old Swiss Confederacy established close contacts. The good neighborly relations ended when revolutionary France invaded Switzerland and established the Helvetic Republic in 1798. Switzerland remained a French vassal state until 1813. At the Congress of Vienna, Switzerland was granted small areas of French territory as compensation and Swiss independence was restored. After that, France respected Swiss neutrality and relations remained peaceful. In the early 21st century, both countries maintain friendly relations.

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008, in collaboration with over 10,000 scientists, and hundreds of universities and laboratories across more than 100 countries. It lies in a tunnel 27 kilometres (17 mi) in circumference and as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.

The first collisions were achieved in 2010 at an energy of 3.5 tera-electronvolts (TeV) per beam, about four times the previous world record. The discovery of the Higgs boson at the LHC was announced in 2012. Between 2013 and 2015, the LHC was shut down and upgraded; after those upgrades it reached 6.5 TeV per beam (13.0 TeV total collision energy). At the end of 2018, it was shut down for maintenance and further upgrades, and reopened over three years later in April 2022.

The European Organization for Nuclear Research, known as CERN (/sɜːrn/; French pronunciation: [sɛʁn]; Organisation européenne pour la recherche nucléaire), is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in Meyrin, a western suburb of Geneva, on the France–Switzerland border. It comprises 24 member states. Israel, admitted in 2013, is the only full member geographically out of Europe. CERN is an official United Nations General Assembly observer.

The acronym CERN is also used to refer to the laboratory; in 2024, it had 2,704 scientific, technical, and administrative staff members, and hosted about 12,406 users from institutions in more than 80 countries. In 2016, CERN generated 49 petabytes of data.

Morzine (French pronunciation: [mɔʁzin]; Arpitan: Morzena), alternatively known as Morzine-Avoriaz (pronounced [mɔʁzin avɔʁja]), is an alpine commune on the Swiss border in the Haute-Savoie department in the Auvergne-Rhône-Alpes region in Southeastern France.

It is located in the French-Swiss Chablais historical area, south-southeast of Évian-les-Bains and just west of Champéry in Valais. As of 2022, it had a population of 2,661. The town of Morzine is situated in the French Alps' Vallée d'Aulps (Aulps Valley), which stretches from Morzine to La Vernaz in the northwest.

Ain (/æ̃/; French: [ɛ̃] ; Arpitan: En) is a French department in the Auvergne-Rhône-Alpes region, Eastern France. Named after the Ain river, it is bordered by the Saône and Rhône rivers. Ain is on the country's eastern edge, on the Swiss border, where it borders the cantons of Geneva and Vaud. In 2019 it had a population of 652,432.

Ain is composed of four geographically different areas - (Bresse, Dombes, Bugey and Pays de Gex) - each of which contributes to the diverse and dynamic economic development of the department. In Bresse agriculture and agro-industry are dominated by the cultivation of cereals, cattle breeding, milk and cheese production as well as poultry farming. In Dombes pisciculture assumes greater importance, as does winemaking in Bugey.
