A ruined mansion hidden in the woods of the Hudson Valley, home of a tragically doomed romance.

The remains of what was once the world's steepest passenger funicular.

Home to the abandoned Tioronda Hat Works Factory, this park is a combination of woodlands and marshlands.

This abandoned factory on the Hudson River once churned out a million bricks a week.

A 19th century hat factory still stands as a crumbling ruin in upstate New York.
