Medieval inns appeared in a variety of sizes, but they tended to be very big structures that stood out in a town's environment. The hall, kitchen, stables, storage space (cellar), chamber (loo/WC/toilet/poophole), and accommodation for the innkeeper and his family comprised the basic structure of an inn. The larger the inn, the more facilities it had; the most common type of facility was a kitchen. Inns usually had public rooms where people could eat and drink, as well as private rooms where individuals could go to sleep.
Inn signs were used to identify which rooms were available. They often included pictures or descriptions of the rooms themselves as well as some kind of insignia - a flag, coat of arms, or even just a simple pictogram - that served to indicate what sort of accommodation was offered there. For example, an inn with only single rooms would put up signs indicating this fact by showing a single symbol representing a room.
People usually went to inns to eat and drink, but they also sometimes used them as bases while traveling or as places to stay when passing through a town. Inns often had large gardens or open spaces where people could play games such as archery, tennis, or jousting, or even use them as markets. Inns that served food also often had live music or drama performed for guests.
Inns first started appearing in Europe around the 11th century.
Medieval Castle Rooms
Inns built in important cities, which occasionally provided high-class lodging, were an exception to this norm. Later (in the 1400s), it was usual for a medieval inn to include one or two private function rooms that could be rented by local guilds or for private gatherings. These might be used for dances, plays, and other entertainment during weekends or holidays.
By the 1600s, with the rise of more luxurious hotels, the number of function rooms at inns had dwindled considerably. But they still exist today at some heritage hotels and restaurants that want to offer an authentic experience from centuries past. They're also popular venues for small weddings and parties.
In modern English, a function room is any special area set aside for recreational activities or events.
A series of chambers like this is common in the inside of a medieval castle: Some of the terminology may seem strange since they are no longer in use, but after reading the text, you will have a vivid image of what it was like inside a castle.
The first thing you need to understand about the inside of these castles is that they were not like modern houses or hotels. In fact, they were not like any house you have ever seen before.
They were built for war and violence. The main chamber where the lord of the castle lived had thick walls for protection and to keep out the heat during summer and the cold in winter. This room also had large windows so that he could see anyone who approached his door. There were storage rooms attached to this chamber with more protective walls and small windows. These were used to store food and supplies for the castle.
Other important rooms included the dining hall where the lord and his guests ate every day at a long table without running out of food, the chapel where they prayed to God for help in battle and forgiveness for their sins, and the great hall where they held court and listened to complaints from outside the castle walls. There might be other rooms too but these are the most important one.
Now, back to your question about what was inside these castles.
