Several years ago, Charleston became a home port for Carnival Cruise Lines. As a result, the number of cruise ships and passengers has increased exponentially, creating significant impacts throughout the National Historic Landmark district. North Charleston is one of the state's major industrial centers and is the state's top city in gross retail sales. You will find a wide selection of restaurants, entertainment complexes, shopping malls and specialty shops, not far from any of the local area attractions. North Charleston is also home to Academic Magnet High School, which is consistently ranked as one of the best high schools in the nation.
