Minnesota Children's Museum (MCM) first opened across the river in 1981. It became a big success and moved to St. Paul in 1986 when it outgrew its original building. It eventually found its current home in 1995 which had new exhibits and a pioneering gallery for toddlers. It has continued to expand over the years, and there is even a Minnesota Children's Museum of Rochester that opened in 2012. MCM is a dream come true for children of all ages, and it has several self-directed activities such as a laser maze, a pretend town, and a four-story climber with a spiral slide.
