Building
Inn
Period: 13th–14th century (commercial inn); monastic guest-houses in the 12th
An inn was a house built to lodge travellers, with several chambers and substantial stabling. In the 12th century most travellers' lodging was given by monasteries under the Benedictine duty of hospitality, in guest-houses near the gate offering food, beds and stables. Purpose-built commercial inns appear in the documentary record later; some surviving inn buildings date from the 14th century, when inns and taverns also began hanging out painted signs.
Caveats (confidence: medium)
The date commercial inns first appeared is not well fixed; townspeople certainly took in paying guests in the 12th century, but purpose-built inns are hard to document.
