When the Powder Magazine was built in 1712, South Carolina was a proprietary colony owned by eight British aristocrats. Seven years later, the colonists peacefully overthrew the Lords Proprietor and South Carolina became a royal colony. The flags flying in front of the Powder Magazine symbolizes Charles Towne's connection to the British Empire.
The Cross of St. Andrew
The Cross of St. Andrew is the national flag of Scotland. The white diagonal cross on a blue background represents the martyrdom of Scotland's patron saint, St. Andrew, who was crucified in AD 69 on a diagonal cross.
This flag, commonly referred to as the pre-1801 Union flag, combines the Crosses of St. Andrew and St. George. Dating from the early 1600s, the Union flag became the official flag of Great Britain after the Act of Union in 1707 that joined England and Scotland. The pre-1801 Union flag looks slightly different from the one presently in use. A red diagonal cross was added to the Union flag after Ireland's incorporation into the United Kingdom.
The Cross of St. George
The Cross of St. George is the national flag of England. The red cross on a white background represents St. George, England's patron saint.
