Zanesville, OH is called "Clay City" by the locals and this meadow of beautifully painted giant vases is an homage. With plenty of natural clay deposits Zanesville was once the pottery capital of the U.S. The little park is located right next to the Muskingum River Y Bridge right off of West Main Street. It's open to the public and free of charge. You might want to consider visiting some time in July when the Zanesville annual Pottery Festival takes place.
Cool but sad. Run down. Could be amazing!
