What To See In Gettysburg

I’m planning a trip to Gettysburg and I’m wondering what I should see while I’m there. I’m interested in learning about the history of the Civil War and the Battle of Gettysburg, so I’m hoping to find some sites that will give me an in-depth look at the battle and its aftermath. I’m also interested in learning about the town’s culture and heritage, so I’m looking for sites that will give me a better understanding of the area. I’m hoping to find some museums or monuments that will help me gain a better understanding of the history of the area, as well as some other attractions that will give me a better appreciation for the area. Any advice or suggestions on what I should see while I’m in Gettysburg would be greatly appreciated.
