Professor Jung Jin Yeoul of the Department of AI Design at Kookmin University has unveiled a large-scale public design project titled 《SEOUL DAY & NIGHT LETTERING》, commissioned by the Seoul Metropolitan Government. The project utilizes approximately 2.5 kilometers of construction barriers installed along the construction site of the “Yeongdong-daero Intermodal Transit Center.”

This project was conceived to transform the construction site environment from a simple barrier into a cultural symbol of the city, and was realized through environmental typography that blends Seoul’s tradition with a contemporary urban sensibility. Installed continuously along the entire 2.5-kilometer-long barrier, this work is drawing attention as an example of how a transitional space within urban infrastructure has been reconfigured into a single visual narrative.

《SEOUL DAY & NIGHT LETTERING》 is characterized by its reinterpretation of various visual elements of Seoul—such as the colorful paintwork of royal palaces, traditional wrapping cloths, antique furniture decorations, and apartment facades—into typographic structures, centered around the message “SEOUL MY SOUL.” Professor Jung Jin Yeoul explained, “This project is an attempt to interpret the city of Seoul as both a text and an experience,” adding, “It was designed so that citizens could naturally experience the city’s identity and aesthetic sense even amidst the temporary circumstances of construction.”

This project is recognized as a case study that visually embodies urban identity through the use of typography in a large-scale public space, presenting new possibilities in the fields of public design and environmental graphics.
