Since the DCM opened its doors on April 24, 2010, it has welcomed over 390,000 guests from all over the region.  Children's museums light creative sparks that last a lifetime and result in objective and quantifiable learning. They create safe, enriching places where kids and their families can share inspired fun and see new possibilities unfold. More than 400 children's museums have been built worldwide, over half of them in the last 30 years. Delaware is one of a handful of states that, until recently, did not have a children's museum.
