Twin towns and sister cities are two towns in different places that decide to become 'twinned' or 'sister' cities - this means they promise to be friends and help each other out in different ways. For example, they might help each other with cultural activities, like providing resources for festivals, exhibits, and performances, or sports and educational cooperation. Twinning towns also have agreements about helping each other with economic projects, public works, and other activities. Being a twin town or sister city is a way for two cities to make a real connection, no matter how far away from one another they may be.
