Baltimore, Maryland is among the more enjoyable stops on the east coast, and its closely knit neighborhoods and historic quarters provide an engaging backdrop to many diverse attractions, especially those along its celebrated waterfront , like the Inner Harbor's National Aquarium and the Pier 6 Concert Pavilion and Power Plant entertainment complex. The city also boasts top-rated museums , like the Walters Art Museum and the child-oriented, interactive Port Discovery, which cover everything from fine arts through black history to urban archeology. That Baltimore has been home to such diverse figures as writers Edgar Allan Poe and Anne Tyler and civil rights activists Frederick Douglass and Thurgood Marshall goes some way towards explaining its sometimes bizarrely varied character.
