Athens America, also known as the Athens of America, refers to the city of Boston, Massachusetts. It got this nickname due to its rich history, architecture, and education - similar to that of Athens, Greece. However, there are no exact synonyms for this phrase, as it's a nickname unique to Boston. Some other American cities, such as Philadelphia, have also been nicknamed the Athens of America due to similar reasons. Still, none of those places can be called Athens America without reference to Boston, which remains famous for its universities, museums, and historical sites.
