Located at an elevation of 5,118 feet, Davos is the highest city in Europe. The community with just 10,000 inhabitants registers over 2.1 million visitors a year. The valley was only inhabited in 1280 – late for European standards – and the area was mainly used to graze cattle. The fortunes of the city began to rise in the 1850's when the mountain air was deemed to be good for tuberculosis sufferers. A sanatorium for lung patients in Davos is the setting of Thomas Mann's famous novel “Magic Mountain”. The role of the city as a resort for winter sports began when a toboggan race was held there in 1883. During the summer months, however, Davos is a much quieter place and an excellent base for hiking and sightseeing trips to the surrounding peaks and valleys.
