I stumbled upon this museum on my way to the National World War II Museum.
The sign outside the Confederate Memorial Museum was a bit misleading.
While I likely would have visited it regardless, the sign seems to indicate a "Civil War" museum, while the vast majority of the artifacts within the museum were from the Confederate states (and more specifically Louisiana).
I believe the official name of the museum is "Louisiana's Civil War Museum at Confederate Memorial Hall" which is definitely a more accurate description.
Compared to the National World War II Museum (a block over) this museum can seem quaint, but I was impressed by the collection of actual artifacts from the war and the era.
However quaint it might feel, the museum is the oldest in Louisiana and houses one of the largest collections of Confederate memorabilia in the United States.
There was very little narrative in the museum, which let the artifacts shine and speak for themselves but for those wanting a timeline or better understanding of events surrounding the war they may not find that by simply visiting the museum.
The museum also hosts a number of personal pieces from Jefferson Davis, the only president of the Confederacy and as I understood from the museum exhibits, one of the founders of the museum.
A worthwhile visit if you're in the area -- especially if you're a history or Civil War buff.
