The designs of a grand house and Charleston may be best seen in the work of the Manigault House. Prior to the US Civil War they were one of the wealthiest families in the country.

Manigault studied in Europe and also designed the Charleston US Bank building (now city hall) among others.
The winding stair case here is a favorite of architectural students (and me) since it was one of the first created in the US with this style.
Recently I stopped by to shoot the interior again and try for different angles and light.
I need a large black and white for a metal print and now think perhaps one from this day might work.
