Which South Carolina city is named as a leading city for United States Semiquincentennial events?

Charleston, South Carolina, is named as a leading city for United States Semiquincentennial events.

The 2016 legislation directing anniversary planning identifies locations of historical significance to the United States. It specifically lists Boston, Philadelphia, New York City, and Charleston, South Carolina, as leading cities for related activities.

Charleston’s inclusion reflects its central role in colonial and Revolutionary-era history. South Carolina was one of the thirteen colonies, and Charleston was an important port, political center, and military target during the American Revolution.

Charleston should not be confused with Columbia, the modern state capital. The question concerns the city named in the semiquincentennial legislation, not the capital city or every community hosting local anniversary programs.
