The term public house only came into popular use in the 17th century. Before this, there were several types of place which could loosely be described as a "pub", which Jennings divides into the following categories: inns (designed primarily for travellers), taverns (which specialised in wine), and alehouses. This is the galleried courtyard of a typical inn, the Bull and Mouth in London, pictured around 1806.
