The Jangsu-dong ginkgo became a nationally designated Natural Monument on 8 February 2021. Its former Incheon Monument status was revoked the same day, so old and current listings must be sequenced. Age claims are estimates, not a counted germination year. Soil, drainage, branch support and protection are part of its survival.
Use dated official sources and check current hours, closures, tides, construction and transport. Separate production from sale, original traces from reconstruction, workplace from attraction, proposal from completion, and a single observation from a district-wide conclusion. Stay on public routes and obtain consent before photographing people or interiors.
