Andrew Jackson never liked being referred to as "President"...he preferred "General." That bit of trivia - and many, many more - will be learned on a visit to The Hermitage.
The movie provides a good overview of what you will see on your visit.
The audio tour of the museum and mansion grounds is HIGHLY recommended. Each audio tour is 3 audio tours in 1: a version for adults, a version for kids, and a version with insights into General Jackson's beloved wife (and source of scandal) Rachel.
The mansion is a short walk through the well-manicured grounds. Upon arriving at the mansion, you will be greeted by knowledgable interpretive tour guides. Many items in the home are original, including much of the furniture and even the wallpaper!
Should you wish to continue exploring the grounds, you will walk through a beautiful garden en route to the small family cemetery, including the tomb of General Jackson, Rachel, and even "Uncle Alfred" nearby. You will also see Uncle Alfred's quarters, slave quarters, and the original Hermitage log cabin (with the first floor removed).
Throughout this trip back in time, you will gain new insights into what life was like in those days, and how times have changed.
Eat before you go and wear your walking shoes, as there is a LOT of ground to cover. Plan on spending AT LEAST 2-3 hours at the site.
