Gas Works Park is an old gasification plant turned into city park on the North shore of Lake Union. It is the only remaining remnants of a coal gasification plant in the United States. The park has a beautiful view of downtown Seattle (including the Space Needle), the I-5 Ship Canal Bridge and the Aurora Bridge (officially, the George Washington Memorial Bridge). Gas Works has a lot of wide open space, an artificial hill for flying kites, and outdoor movie nights during the summer. Unfortunately, as you might imagine, the park has some environmental issues. Oil would bubble up from the ground on hot days, though that apparently has been “fixed,” and ground contaminants are leaching into Lake Union. So the park is closed every now and then for testing and cleanup. Still, Gas Works Park is one of the more interesting parks in Seattle and the nation.
