Imposing means grand and impressive in size or appearance. An imposing building, an imposing figure, imposing gates.
It is about scale and presence rather than beauty — an imposing building need not be handsome, only large enough to affect you. Applied to a person it means physically commanding. Note impose, which means something quite different and mostly negative: imposing a rule, or imposing on somebody's kindness.
