Formerly known as Lied Discovery Children's museum, this 58,000-square-foot (5,400 m2), three-story space is now located adjacent to The Smith Center in Downtown Las Vegas.

The DISCOVERY Children's Museum was founded by Robin Greenspun and Mark Tratos in 1984.

The pair arranged a partnership between the Junior League of Las Vegas and the Allied Arts Council to fund a much-needed nonprofit educational institution in the Las Vegas Valley.

In 1985, a bond issued to authorize the building of the Las Vegas-Clark County Library and Lied Discovery Children's Museum, which opened its doors on September 9, 1990.
