Seattle Monolith, Steel sculpture on Kite Hill in Magnuson Park, Seattle, United States.

The Seattle Monolith is a hollow steel structure measuring 1 by 4 by 9 feet (0.30 by 1.2 by 2.7 meters), matching the proportions of the Monoliths in 2001: A Space Odyssey. Louie Raffloer fabricated it at Black Dog Forge from 16-gauge steel and L-beams, with rebar protruding from the bottom to anchor it to a foundation of four steel tubes set in concrete.

On New Year's Day 2001, a replica of the Monolith from 2001: A Space Odyssey appeared on Kite Hill in Magnuson Park, made by artists calling themselves Some People. After it was removed from the park it was found on Duck Island, and Caleb Schaber came forward as spokesperson. Two years later Chris Lodwig told the Seattle Times that he, Titus Grupp and Eric Leuschner had the initial idea, with about 50 people involved.

The sculpture references the mysterious object from the film 2001: A Space Odyssey, creating a connection between cinema and public art. Its black steel form stands out in the urban landscape like an unexpected visitor.

The monolith sits in a public park with nearby parking and bus connections for convenient access. The sculpture is outdoors year-round, so plan your visit with weather in mind.

The $250 budget came largely from an "Apes of Wrath" Mexican wrestling party at Rocket Science Studios on Westlake Avenue, plus T-shirt sales and a Broadway bake sale. Chris Lodwig, Titus Grupp and Eric Leuschner had the original idea; about 50 people helped. Caleb Schaber later posed as the group's spokesman and ran for Seattle mayor in April 2001.
