The Illinois Historic Preservation Agency (IHPA) operates over 60 historic sites and memorials. The Agency also administers the Abraham Lincoln Presidential Library and Museum. The library is the state’s chief historical and genealogical research facility that is home to the state’s world-renowned Abraham Lincoln collection. The library houses the Agency's collection of more than 12 million items of Illinois history. The museum combines scholarship and showmanship to communicate the amazing life and times of Abraham Lincoln in unforgettable ways and features many of our Lincoln artifacts as well as two main theaters. We administer all state and federal historic preservation and incentive programs in Illinois, including the National Register of Historic Places. Thank you for visiting.
