Depending on when you visited this building the now back was actually the front. Yeah, it is confusing.
The photograph above is the original front entrance to the plantations main building. It really is beautiful with the large full porch.
However, it is not what we would consider the typical plantation with the huge front columns. After the civil war was over the back of the building became the front. Big white columns and large windows were added to be what the world (at that time) thought a plantation building should look like.
And of course this was done to impress people with their wealth (which was gone after the war).
