A castle is a fortified dwelling designed to shield its inhabitants from outside threats. There were kings and lords who were in command, warriors who protected the castle from outsiders, and even chefs and cleaners who made sure everyone was fed and the place was kept immaculate. A lot of people could be jammed into such areas.
Castles often had walls on all sides, and these walls might be of varying thicknesses. Many areas of the castle have their own unique, occasionally contrasting, designs. Castles with two walls, one on the inside and one on the outside, were known as concentric castles, and they were used as an extra line of defense.
