INN

building that affords public lodging, and sometimes meals and entertainment, to travelers. The inn has been largely superseded by hotels and motels, though the term is often still used to suggest traditional hospitality. Inns developed in the ancient world wherever there was traveling for trading purposes. Ancient Persia's extensive highway system featured inns. Along caravan routes, caravansaries appeared. These were placed approximately eight miles apart and were often constructed as forts with watchtowers. A smaller-scale structure, the khan, developed in towns. Roman inns apparently were laid out in the same manner as ancient villas. Stables and accommodations for sleeping and eating were placed around one or more centralized courtyards. During the early Middle Ages, accommodations for travelers were usually to be found only in monasteries; but under the combined influence of the revival of commerce in the late medieval period, the Crusades, and an increase in the popularity of pilgrimages, lodging houses were built by monasteries, guilds, and private entrepreneurs. In Great Britain inns numbered about 6,000 by the late 16th century. European inns of that period were planned around the sides of a courtyard, were several stories high, and featured arcaded or balustraded galleries above the ground level.
