About Rochester

Learn more about the host city, Rochester.

Big-city culture and small-city charm combine in Rochester, a mid-sized city on the shore of Lake Ontario. The birthplace of amateur photography, Rochester was synonymous with Eastman Kodak for much of the 20th century, but the city's fame was established well before George Eastman came on the scene. Today, its historical treasures complement modern family-friendly attractions that rival those found in much larger communities.
