Powder Magazine Museum

Locals and history enthusiasts regard the Powder Magazine as a genuine colonial gem — South Carolina's oldest public building (1713) and a National Historic Landmark — but temper expectations: it's a very small, self-guided space that some feel isn't worth the ~$8 admission on its own without a walking tour. Knowledgeable staff and volunteers are consistently called out as the real draw, making the compact exhibits feel worthwhile, while ghost-tour crowds are also drawn by its reputation as one of Charleston's most haunted spots.
