#4: Seattle’s Gum Wall
Art’s subjectivity is questionable at Seattle’s Gum Wall, adjacent to Market Theater. Initially, a quirky spot where patrons adhered pennies with gum, this attraction has grown exponentially, transforming into an admittedly gross spectacle bursting with communal creativity.

The spectacle of millions of gum pieces blanketing Seattle’s Gum Wall transcends mere visual impact, highlighting hygiene concerns. Ranked among North America’s top five germiest tourist spots, it serves as a vivid, if questionable, testament to communal art’s unexpected consequences.
