From the article....
The museum would rise on 78 of those acres, on a hillside that offers sweeping views of the Schuylkill and Valley Forge National Historical Park. If all goes according to plan, construction would start by the summer of 2008. Talk about a museum began in 1995.
The center will house more than 15,000 rare documents, artifacts, weapons and other materials, many of which have never been publicly displayed.
"The time for a center to commemorate the American Revolution and the independence of our nation is long overdue," said H.F. "Gerry" Lenfest, chairman of the board of the American Revolution Center (ARC). "Now we have the opportunity to make it a reality."---
Sounds like it is still a way's off but if it does happen I think residents and business owners alike will benefit greatly by this.
