Romantics were much more concerned with things they could own than with nature. Romantics also never saw a factory. Wrong era.
You could write about a pretty place you have been too! something like this maybe?
I would say one of the most prettiest places I have seen is a beach in Virginia. To get there, you had to walk a couple of miles through a beautiful forest. The forest was so green and the heat of the sun was very hot but the trees covered us with cool shade. Once we got there, we relaxed and cooled off in the water. I felt happy and calm, I would love to do it again some time!
