Today, on Lincoln's birthday, we look back at an important moment in Springfield history.
The date was April 19, 2005. The Abraham Lincoln Presidential Museum opened, six months after the Library began operation. President George W. Bush spoke at the ceremony.
This coming April will mark the 10th anniversary of museum, which has become one of Illinois' top tourist attractions as well as a place for people to learn more about the man whose name is on the building.
