I am full of cities, but have no buildings I am covered by forests, but have no trees I have lakes, rivers, and oceans, but hold no water I have both the largest and smallest populations, but have no people

I'm a group, a place, a hardened state, I lower with sun or seal your fate. I'm staged for scenes on screen or play, Yet once I'm down, I tend to stay.

In the darkest black with a metal skin, I warned of an attack, One if by land, two if by sea A nation soon to be free

I’m a prismed shell that drinks the sun, yet shelters no person when day is done. Within my walls, the green convene, In silent warmth, a hidden scene.

I have three legs, sometimes four I help you rest, when your feet are sore Of sizes I am many, but my structure stays at core Reading upright, you might be near me so much more
