Public controversy has emerged regarding the use of generative artificial intelligence in urban art and design. In Gniezno, Poland, a mural depicting King Bolesław Chrobry faced backlash after critics labeled it an ‘AI mess,’ noting that competition rules had reportedly prohibited generative AI. While some defended the technology as a tool comparable to Photoshop or AutoCAD, others argued it differs fundamentally from traditional design software.

This incident reflects a broader global trend of ‘AI slop’—low-quality, AI-generated content—appearing in urban environments such as London, San Francisco, and Glasgow. Examples include a Christmas mural in London that was removed following online mockery for its distorted details, and a mural competition in Elbląg, Poland, where AI-generated designs featuring incorrect emblems led the city to change its competition format to allow for resident-submitted proposals.
