Balancing Nature and Innovation: Exploring Urban Harmony in Korea

As part of our ongoing exploration of how Korean culture shapes architecture and the built environment, today’s visits provided a vivid look at how cultural values such as efficiency, environmental responsibility, and harmony with nature are reflected in Seoul’s urban design.

Our day began with a visit to Seoul City Hall, which immediately made a strong impression. As soon as we entered, we were greeted by a towering wall of greenery, transforming the entryway into a vertical forest. This lush plant installation is not only visually striking but also symbolizes Korea’s commitment to incorporating nature into the built environment, a theme that continues throughout the city and reflects Korea's long-standing tradition of harmony with nature.

Inside City Hall, we toured TOPIS (Transport Operation and Information Services), the system that manages Seoul’s extensive public transportation network. Throughout my time in Korea, I’ve noticed an impressive number of cameras around the city, from streets to subways, and during this visit, I learned how these tools are used not just for security, but for managing traffic and enhancing efficiency.

One standout feature is that traffic camera footage is made publicly available via the TOPIS website, allowing citizens to check road conditions and avoid congested areas. Similarly, digital signage near subway platforms and bus stops informs riders in real time whether a particular car or vehicle is crowded, helping people make more comfortable and efficient travel choices.

TOPIS also uses real-time data to adjust traffic lights in response to congestion and track the punctuality of buses. Some systems rely on AI and automation to optimize these adjustments. If a bus consistently runs late, this data prompts corrective measures. Another fascinating use of this system is environmental: Seoul uses vehicle-recognition technology to check whether cars entering the city meet emissions standards. If a car exceeds the pollution limit, the system automatically sends a text message and fine to the vehicle owner. These practices not only encourage the use of cleaner vehicles but also promote public transportation. Korea is also exploring the adoption of hydrogen-powered vehicles, which emit only water vapor and represent a promising innovation in clean energy, as part of its broader sustainability efforts.

In the evening, we visited Seoullo 7017, an elevated park that once served as a highway overpass. Similar to Cheonggyecheon Stream, which was restored from a covered waterway into a vibrant public space, Seoullo 7017 represents Seoul’s commitment to transforming outdated infrastructure into places that foster community and reconnect people with nature.

The park features over 160 species of native Korean plants, celebrating Korea’s ecological heritage. Along the pathway are circular structures that serve various purposes, such as cafés, small galleries, and even a piano space where passersby can stop and play. Some structures include rooftop platforms that offer elevated views of the city, providing a peaceful contrast to the dense urban surroundings.

Seoullo 7017 was clearly designed to be enjoyed at any time of day. The path is lined with soft lights, many of which are solar-powered, that add a warm glow at night and complement the city skyline. The space invites people to walk, relax, and enjoy nature in the middle of one of the world’s busiest cities.

After today’s visits, I saw clearly how Korea places high value on efficiency, technological innovation, and nature. TOPIS showcases innovation and convenience through the use of cameras, GPS, autonomous systems, and environmental monitoring. Seoullo 7017 represents how tradition and nature are honored through thoughtful design, with its variety of native plants and spaces that bring people together. The only city I’m familiar enough with to compare Seoul to is New York City. One big difference is how nature is distributed. In Seoul, greenery is integrated throughout the city, from rooftops to streetscapes, whereas in New York most greenery is concentrated in designated parks. What both cities share, though, is a commitment to making public spaces that foster community.

This blending of advanced technology with eco-friendly, people-centered design reveals the depth of Korean cultural values. The efficiency of TOPIS reflects Korea’s fast-paced, solution-driven mindset, often described by the phrase ppalli ppalli (meaning hurry hurry), while places like Seoullo 7017 show how Korea continues to value nature and heritage even during rapid urban growth. Korea creates a powerful balance between modernization and tradition, showing that the two can coexist and even enhance one another through thoughtful and intentional design.
