The Unseen World - Season 2 (2021)

The story behind a one hundred fifty thousand-square-foot, ten-story playground and the man who brought it to life. Then, how the discovery of a single fossil led to the creation of a drive-through museum and kick-started a folk-art career you should really bone up on.

The story of a man who built the mile-long stone wall that wraps around an Alabama forest and the woman who inspired it. Then, the man-made cave buried on the grounds of a funeral home.

The man who wrote a journal to himself out of salvaged steel and water towers. And the eclectic museum at its feet.
