Each evening the Bars were closed and the city shut in for the night. Defenders used a Bar as a watch-tower or a fort. They could walk along the high crenellated walls of the Barbican and shoot thence, and stop the way by lowering the portcullis.1 Near the Castle there were the Castle mills, where the machinery was driven by water-power. Outside the walls there were strays, or common lands. Some of the land immediately around the city was cultivated or used as pasture.
