Once the ranger’s informative talk was over, Mum and Trixie stayed on the parade grounds, while Pops scaled the stairs to the upper deck, atop the back bunker to get views of the hazy horizon. Here the forward portion of the old fort is filled in with earth, as the black bunker fills up much of the interior – the seaward brick wall is not much more than a façade.
The mid-deck, where the disappearing gun position was on the northern side, is now a mini-museum, with a model of how the fortress looked in its prime, samples of the artillery in use, and the ruined remains of the Palmetto State flag that was raised when it surrendered; it is a faded green square, little better than a bedsheet that would be hard to identify at a distance. The centerpiece of the museum is the storm flag that was removed by the commander at the end of the siege, and then returned at the end of the war to fly once again when the fort was reclaimed by the Union. It site in the center of the counterweight well of the old disappearing gun position. A museum store fills up the old shell elevator area, and a more conventional gun mount on the southerly side.
