The Liberty Bell
The Liberty Bell's future home on 6th Street between Market and Chestnut Streets will provide visitors with a glorious view of Independence Hall. The new Liberty Bell Center will incorporate three discrete but physically and thematicaly connected elements: a shaded outdoor arcade containing educational materials, an inside interpretive exhibit hall, and a new chamber for the Bell. In this new configuration visitors will have a chance to gain an understanding of the Liberty Bell's history and the many inspiring stories associated with it. The exhibits will be a fitting prelude to their personal and often emotional encounter with the nation's most recognized icon of freedom.
