Which country is the home of the natural ice skeleton racing toboggan track the 'Cresta Run'?

The Cresta Run is a natural ice skeleton racing toboggan track in eastern Switzerland. Located in the winter sports town of St. Moritz, the 1.2125 km (0.753 mi) run is one of the few in the world dedicated entirely to skeleton. It was built in 1884 near the hamlet of Cresta in the municipality of Celerina/Schlarigna by Major Bulpett, eventual founder of the St. Moritz Tobogganing Club (SMTC), George Robertson & Charles Digby Jones (Robertson and Digby Jones planned the proposed course), C Metcalfe and J Biddulph (the 5 making up the Kulm Hotel's Outdoor Amusement Committee) and the people of St. Moritz. It has continued as a partnership to this day between the SMTC, founded in 1887, and the people of St. Moritz.

The sport of sled racing originated around the nascent winter resort activities at the Kulm hotel in St. Moritz during the winters of the early 1870s, and today's members still congregate for lunch in the 'Sunny Bar' at the Kulm. In the early days of competitive sledding, the predominant style was luge-style racing lying on one's back, but the invention of the flexible runner sled (Flexible flyer) in 1887, known colloquially as 'the America', led to Mr. Cornish using the head-first style in the 1887 Grand National. He finished fourteenth due to some erratic rides but established a trend and by the 1890 Grand National all competitors were riding head-first. The head-first style for a time became known as 'Cresta' racing.
