This sculpture makes a perfect frame for the boats in the bay. You can have different content in the circle, depending on where you stand. Bayfront Park, Sarasota is the site of many sculptures. They periodically run contests along the length of the park to exhibit a variety of art.  I don't know if this piece was part of one of the contests or not. It may have been a piece that was purchased for the park. I have used The Circle on several occasions when I was doing family portraits.
