Thanks to some posters on the Charleston reddit page, I was able to see these two interesting videos.
The first takes the viewer inside the Morris Island Lighthouse, while the second explores the mysterious Castle Pinckney out in the Charleston Harbor.
The lighthouse video is about a year old, so it should be an accurate representation of what the structure looks like today. The video of Castle Pinckney was shot by WCBD News 2 over 3 years ago, which was before some of the brush and debris were cleared away.
You can watch both below.
