The precursor to the modern hotel was the inn of medieval Europe. For a period of about 200 years from the mid-17th century, coaching inns served as a place for lodging for coach travelers. Inns began to cater to richer clients in the mid-18th century. One of the first hotels in a modern sense was opened in Exeter in 1768. Hotels proliferated throughout Western Europe and North America in the early 19th century, and luxury hotels began to spring up in the later part of the 19th century.
