At Paengmok Harbor, alongside a memorial sculpture honoring the Sewol ferry victims, stand the "Lighthouse of Waiting," the "Wall of Remembrance," and the "Mailbox to Heaven."
There are feelings words cannot fully carry. People have placed those feelings into a lighthouse, a wall, and a mailbox instead. The lighthouse holds the waiting for those who did not return; the wall holds the vow not to forget them; the mailbox holds letters sent to a place that can no longer be reached.
