The building, which was built as a hotel in 1809 and converted to a theater in 1935, occupies the site of the first building in the Thirteen Colonies designed for use as a theater. The first opera performed in the new country was at the first Dock Street theater.
It has been on the National Register of Historic Places since 1973.
And yes, some nights you can even get a drink. I believe they still serve Planters Punch here in the Planters Hotel bar (now the Dock Street Theater).
During the Civil War the hotel was one of many buildings severely damaged and was almost torn down. The town of Charleston finally repaired it.
If there are no activities or shows the doors are opened and you can walk in and visit around the old rooms upstairs as well as the theater itself.
