Graffiti makes a city’s landscape beautiful while simultaneously being considered illegal and violating a city’s cleanliness and respect for public spaces. To solve these problems, we present metaverse virtual-world technology. Within the metaverse, graffitists can freely create, share works, and express themselves through graffiti art by virtually reproducing the walls or public facilities of a city. The created virtual space used by the graffitists in this paper is Sungnyemun, a traditional Korean heritage site. When comparing Roblox PC content and VR content experiences through IPQ surveys, it was confirmed that participants in the VR content experienced a high level of realism and local presence. Accordingly, there is a new possibility for graffiti to be recognized as a form of urban culture and artistic expression through the metaverse.
