What is "coaching inn"

In Europe, from approximately the mid-17th century for a period of about 200 years, the coaching inn, sometimes called a coaching house or staging inn, was a vital part of the inland transport infrastructure, as an inn serving coach travellers. Just as with roadhouses in other countries, although many survive, and some still offer overnight accommodation, in general they have lost their original function and now fulfil much the same function as ordinary pubs. There are few motels with the function of refueling to motor vehicles, but the feeding function to horses was required for coaching inn.
