The park was designed to incorporate industrial ruins rather than removing them, a pioneering approach in post-industrial landscape architecture.
The central hill, known as the Great Mound, sits atop the site's original waste remediation area and offers a panoramic view of the lake.
The park’s boiler house has been repurposed into an open-air picnic shelter featuring original metal machinery.
Gas Works Park was the site of a coal gasification plant that operated from 1906 until 1956.
The park's Sun Dial is located on the top of the Great Mound and uses the observer's own shadow to indicate the time.
The structures are painted in bright, contrasting colors to soften the industrial appearance while highlighting their mechanical origins.
Gas Works Park is an iconic 19.1-acre public space built on the site of a former Seattle Gas Light Company gasification plant. The park features the remaining iron-and-steel industrial structures, which were integrated into the landscape design by landscape architect Richard Haag. It is located on the north shore of Lake Union, providing a distinct view of the downtown Seattle skyline across the water. The park is anchored by a large grass-covered hill, originally constructed from industrial refuse and rubble. Visitors can explore the preserved boiler house and exhaust tower, which serve as prominent industrial artifacts. The park is designated as a Seattle City Landmark and is listed on the National Register of Historic Places.

Bring a kite, as the Great Mound acts as a natural wind tunnel perfect for flying.
The park has limited shade, so bring sun protection even on partly cloudy days.
Avoid entering the fenced-off machinery areas, as they are strictly prohibited for public safety.
Do not attempt to climb or enter the restricted industrial structures, as they are structurally compromised.
Stay within marked pathways and mowed areas; keep dogs leashed at all times.
