Sesame Place is a children's theme park and water park, located outside of Philadelphia in Middletown Township, Bucks County, Pennsylvania. It is the older of two theme parks in the United States based entirely on the children's educational television program Sesame Street (the other is in San Diego, California) and includes a variety of rides, shows and water attractions suited to young children. It is also the first theme park in the world to become a certified autism centre.
