The main cliff inscription is the centrepiece of the entire site — a pair of enormous Chinese characters carved into granite above the beach that have given this headland its name and emotional weight for three centuries. Standing beneath them, you can read "天涯" (Tianya, Edge of Heaven) and "海角" (Haijiao, Corner of the Sea) on separate boulders, carved at different times by different officials, though popular memory has merged them into a single statement.
The calligraphy itself is impressive at this scale — each stroke deep and confident despite the medium. The boulder faces the sea, and the inscription was clearly meant to be read from the water by anyone approaching from the south, arriving at what Chinese imperial geography considered the absolute southern limit of civilisation. Bring your patience on weekends, when tour groups position themselves for photographs at length.
