One unique aspect to N Seoul Tower is the collection of love locks that adorns the rails of the surrounding platform. Thousands of visitors from all around the world have attached locks to chains that have been strung around the deck. Many locks include notes and are meant to be symbols of enduring love. Unlike other locales, where love locks are periodically removed from public spaces, the proprietors of N Seoul Tower seem to encourage the practice. Locks are sold in the gift shop and there is even a special red box for depositing keys (as opposed to throwing them over the railing into the forest for birds to pick up).
