Zermatt is a municipality in the district of Visp in the German-speaking section of the canton of Valais in Switzerland. It has a population of about 5,800 inhabitants and is classified as a town by the Swiss Federal Statistical Office (FSO).It lies at the upper end of Mattertal at an elevation of 1,620 m (5,310 ft), at the foot of Switzerland's highest peaks. It lies about 10 km (6.2 mi) from the over 10,800 ft (3,291.84 m) high Theodul Pass bordering Italy.Zermatt is famed as a mountaineering and ski resort of the Swiss Alps. Until the mid-19th century, it was predominantly an agricultural community; the first and tragic ascent of the Matterhorn in 1865 was followed by a rush on the mountains surrounding the village, leading to the construction of many tourist facilities. The year-round population (as of December 2017) is 5,643, though there may be several times as many tourists in Zermatt at any one time. Much of the local economy is based on tourism, with about half of the jobs in town in hotels or restaurants and just under half of all apartments are vacation apartments. Just over one-third of the permanent population was born in the town, while another third moved to Zermatt from outside Switzerland.The name of Zermatt, as well as that of the Matterhorn itself, derives from the alpine meadows, or matten (in German), in the valley. The town of Zermatt lies at the southern end of the Matter Valley (German: Mattertal), which is one of the lateral branches of the grand Valley of the Rhône. Zermatt is almost completely surrounded by the high mountains of the Pennine Alps including Monte Rosa (specifically its tallest peak, named Dufourspitze), Switzerland's highest peak at 4,634 metres (15,203 ft) above sea level.Zermatt is traversed by the main river of the valley: the Matter Vispa, which rises at the glaciers at the feet of the highest peaks: the Gorner Glacier on the east side near Monte Rosa and the Zmutt Glacier on the west side between Dent d'Hérens and Dent Blanche.To prevent air pollution, which could obscure the town's view of the Matterhorn, the entire town is a combustion-engine car-free zone. Almost all vehicles in Zermatt are battery driven and almost completely silent. Electric vehicles are allowed for local commerces. The Cantonal police can issue a permit which allows residents to drive and park at the northern outskirts and for the permission to be bring combustion engine vehicles in to the town such as construction vehicles. Emergency and municipal vehicles, (fire trucks, ambulances, police etc.) generally use combustion engines, although even some of these are non-combustion, (garbage trucks, etc.).
