My first is the antonym of heavy. My last another word for dwelling. Together I'm a tower with a panoramic view.

In one, you see sculptures and drawings, and in another, you see our ancestors' doings. There's also one where you see scientific innovation, and one where you see animal bones and vegetation. Some are free to enter, some need a price.

I speak without a mouth, I hear without ears, I spin your words back around at you, And you might find my voice unfamiliar

Before jets cut paths through heaven’s blue, I ruled the skies with stately view. Born of gas and counted seams, A floating titan of Kaiser dreams.

In the breeze, I dance with glee, on a playground, find me free. To and fro, I glide in air, a joy for all, beyond compare.
