Lines carved into stone can be pictures and records. Ulsan Petroglyph Museum's exhibition 'Time Repository: Data of the Day' runs from July 7, 2026 until April 25, 2027 in its first-floor special gallery. The museum's own individual exhibition page confirms the title, venue and dates.
Reporting at the July opening describes a project marking the first anniversary of World Heritage recognition for the Bangudae-area petroglyphs. One section looks at prehistoric marks at Bangudae and neighboring sites; another traces inscriptions at Cheonjeon-ri and carved writing from the Silla period. The final section considers rediscovery, research and conservation leading to international recognition.
The exhibition can be paired with a visit to the actual petroglyphs, either before or afterward. Material presented indoors can make the sometimes faint markings easier to appreciate. The museum is at 254 Bangudaean-gil, Dudong-myeon, Ulju-gun, Ulsan. The official individual listing does not clearly confirm admission charges, daily opening hours or reservation requirements, so check before setting off.
