For those with only a short time in Charleston, a combination ticket to visit the Nathaniel Russell House and the Aiken-Rhett House is a good idea. The Aiken-Rhett House has been preserved and has been practically untouched (other than maintenance) since 1858. Seeing these two homes gives the visitor an idea of how much effort goes into the homes' renovation.
Charleston citizens began preserving and renovating the 3000 structures in the historic district of Charleston in the 1920's. Today, six of the homes are museums and open to the public.
