Welcome to the Charleston Historic District. You are standing in a place where history is not just preserved in museums, but lived on every cobblestone corner. Take a deep breath—that salt air is coming straight from the harbor where the Ashley and Cooper Rivers meet. To orient yourself, look around the intersection of Broad Street and Meeting Street.[12] [10] [13] [11] [14] This is famously known as the Four Corners of Law. It is the only place in the United States where four distinct types of law face each other: federal law at the United States Post Office, state law at the Charleston County Courthouse, municipal law at City Hall, and what locals call God’s law at Saint Michael’s Episcopal Church. As you begin your walk, notice the clip-clop of carriage horses; it is a sound that has echoed through these streets for over three hundred years.
