Empty and boring
We went in December and it was unusually cold. Perhaps that colored our experience but we felt snookered. The house is empty. If you have visited other historic buildings and are familiar with the architecture, there isn't much to see or to learn.
Hats off to the people who felt history but my personal feeling is that the people who lived here did not exist in an empty box. I want to see what THEY saw, not a bunch of walls, sanded so I can see 7 layers of paint. Only watching the actual paint dry would have been more boring.
If you do not speak the code of "preserved" as opposed to "restored", you may not realize that this means empty and abandoned looking. And they never plan to do anything else with it! There are many other similar historic buildings in the Charleston area, such as the Aiken-Rhett house. I've never been in a crack house, but aside from the grafitti, I imagine they look a lot like these empty shells.
