Seattle Center’s legacy of providing residents and visitors access to world-class arts, education, and recreation opportunities in a central location began in 1962 with the Century 21 World’s Fair. The Seattle Center Century 21 Master Plan guides the ongoing redevelopment of the Seattle Center's 74-acre campus in response to the needs of a diverse and dynamic community. More information on the Century 21 Master Plan can be found at the bottom of the page.

As stewards of the campus, the Seattle Center department is actively working on major maintenance, capital improvements, and long-term planning projects, including:

Planning is currently under way for redeveloping Memorial Stadium at Seattle Center. The reimagined, state-of-the-art stadium will be a place for everyone, including year-round student athletics, education, and a diverse array of arts, culture, entertainment, and community events, while creating new open space and transforming the heart of the Seattle Center campus for future generations.

Armory Façade Lighting

The Armory exterior is being restored to highlight the façade’s original architectural characteristics. In addition to improvements already completed, lighting upgrades are underway with anticipated completion in 2024.
The well-loved Artists at Play—an imaginative, artist-created playground in the heart of Seattle Center—will be undergoing maintenance beginning in late 2024. The project will include upgrades to the site’s turf and the installation of a brand new, inclusive swing set. These changes will ensure the attraction remains a safe, engaging, and inspiring experience for artists of all ages for years to come.

Bagley Wright Theatre Exterior Upgrades

The exterior of the Bagley Wright Theatre, home of Seattle REP, will benefit from recladding and replacement of select areas of the roof. Visitors can expect to see scaffolding around the building as the project progresses and some noisy activity throughout the summer months, but theatre operations will continue as usual.
Design work is in process for major upgrades to campus wireless infrastructure, which will result in higher quality service for all visitors. Full project completion is anticipated in early 2026.

The City of Seattle is rebuilding Seattle’s central waterfront. With the removal of the Alaskan Way Viaduct, the City is constructing a 26-block, 20-acre park stretching from Belltown to Pioneer Square.  Seattle Center will be stepping into a partnership with Friends of Waterfront Seattle to manage operations, maintenance, and public safety of Waterfront Park, including the public promenade, Overlook Walk, Pier 58, and Pier 62 – a role formerly held by Seattle Parks and Recreation. Seattle Center brings to the partnership its expertise in managing a complex urban public space with large-scale events, programming, maintenance, and public safety integrated into its core operations. This new role closely aligns with the vision and goals for Waterfront Park operations, while relying on the strong partnership approach Seattle Center brings to its work.

Campus ADA Improvements

New ADA compliant hardware is being installed in the Armory, Fisher Pavilion, Exhibition Hall, parking facilities, and Marion Oliver McCaw Hall.

Campus Facility Condition Assessment

We are currently conducting a facilities condition assessment of our existing buildings and infrastructure to gather data, which provides a basis for determining capital needs to correct current issues and to avoid future facilities deterioration. The goal is to gain a better understanding of current facility conditions to build a solid foundation for capital planning and spending by providing a clear set of objectives based on a snapshot in time prior to committing staff and financial resources. This will also help reduce emergencies, keep our campus running smoothly, and provide for an improved customer experience.
