Looking for ways to cool down in our Famously Hot city in August? Join Historic Columbia for our second annual Historic Columbia Water Balloon Battle on Friday, August 19. Using water balloons, we’ll break into teams to learn about military tactics through history and battle it out on the grounds of the Robert Mills House & Gardens. Afterward, relax with drinks and light hors d’oeuvres on the grounds of this historic site. Attendees must be 21 years of age or older.
