The coaching inn (also coaching house or staging inn) was a vital part of Europe's inland transport infrastructure until the development of the railway, providing a resting point for people and horses. The inn served the needs of travellers, for food, drink, and rest. The attached stables, staffed by hostlers, cared for the horses, including changing a tired team for a fresh one. Coaching inns were used by private travellers in their coaches, the public riding stagecoaches between one town and another, and (in England at least) the mail coach. Just as with roadhouses in other countries, although many survive, and some still offer overnight accommodation, in general coaching inns have lost their original function and now operate as ordinary pubs.
Coaching inns stabled teams of horses for stagecoaches and mail coaches and replaced tired teams with fresh teams. Traditionally they were seven miles apart but this depended very much on the terrain. Some English towns had as many as ten such inns and rivalry between them was intense, not only for the income from the stagecoach operators but for the revenue for food and drink supplied to the passengers. Barnet, Hertfordshire still has an unusually high number of historic pubs along its high street due to its former position on the Great North Road from London to the North of England.
There were many coaching inns in what is now central London. The only remaining one with the galleries to the bedrooms above is The George Inn, Southwark, owned by the National Trust and still run as a pub. Many have been demolished and plaques mark their location. The Nomura building close to the Museum of London on London Wall commemorates the "Bull and Mouth" Inn; Golden Cross House, opposite St Martin's in the Fields recalls the Golden Cross, Charing Cross coaching inn.
A pair of coaching inns alongside the former A5 road or the old Roman road Watling Street in Stony Stratford (Buckinghamshire, England), named respectively 'The Cock' and 'The Bull', are said to have given rise to the term "cock and bull stories." Coaches or the Mail coach would stop in the town on their way from London to the North and many a traveller's tall tale would be further embellished as it passed between the two hostelries, fuelled by ale and an interested audience. Hence any suspiciously elaborate tale would become a cock and bull story. This is a cock and bull story in itself, however; as there is no evidence to suggest that this is where the phrase originated. The phrase, first recorded in 1621, may instead be an allusion to Aesop's fables, with their incredible talking animals. As this slightly predates coaching inns, the names of the two inns could have been a reference to "Cock and Bull stories" as to encourage the passing of such anecdotes within their doors.
