One of the best known Confederate landmarks in Montgomery is the Alabama State Capitol,where delegates from seceding southern states convened to organize the Confederate States of America, and where Jefferson Davis was sworn in as Provisional President of the CSA.
Another of course is the First White House of the Confederacy,  his home while he was in Montgomery; also the Winter Building on Dexter Avenue, where the telegram was sent authorizing Confederate Gen. P. G. T. Beauregard to fire on Fort Sumter.
Montgomery also boasts a Confederate Military Prison (2 Tallapoosa St), in which was housed 700 Union soldiers, most captured at Shiloh. Nearly 198 died in captivity and the survivors were moved to Tuscaloosa in Dec. 1862. It was a pretty rank place from what I have read.
The Montgomery Theatre (62 Monroe St) was opened in Oct 1860. John Wiles Booth performed there and Bryant Minstrels introduced “Dixie” there.
 The Lomax House, the Murphy House and the Rice-Semple-Haardt House have all survived, not only the war but also the razing of so many fine, old homes. Fortunately, the Teague House at 468 South Perry Street also survived. From its front portico was read the order of General James Wilson, USA, placing the Capital of the Confederacy under martial law on April 12, 1865.
