Located on Post Alley near Pike Street, south of the market's main entrance off 1st Avenue, the wall is covered with used chewing gum.
[1] Originating inadvertently in the 1990s, the Market Theater Gum Wall has evolved into a notable tourist attraction and local landmark.
The wall is located in Post Alley adjacent to the box office for the Market Theater, a venue for comedy shows and other small performances.
The coins were later removed, but the gum remained amid several cleanings of the walls under orders from the Pike Place Market Preservation and Development Authority.
[5] On November 3, 2015, the Pike Place Market Preservation & Development Authority announced that the wall would be fully cleaned for the first time in 20 years.
[29] Although officials of the Pike Place Market defined the concern about the gum affecting the brick wall, some may see the participation in sticking up the substance as attributing to collective action.
[33] In January 2024, local artist Rudy Willingham chewed 200 pieces of gum to create a mural of Pete Carroll on the wall shortly after he departed as head coach of the Seattle Seahawks.
