• The grotto caves cover a 0.6 mile stretch along the limestone cliffs overlooking the Yi River in Henan Province.
• The earliest caves to be carved in the late 5th and early 6th centuries in the West Hill cliffs include Guyangdong and the Three Binyang Caves, all containing large Buddha figures standing up to 16ft tall outside the caves
• The sculptural styles, the earlier ‘Central China Style’ and the later ‘Great Tang Style’, had great influence within the country’s cultural history
• The landmark was awarded UNESCO special protected status after the committee agreed that ‘the high cultural level and sophisticated society of Tang Dynasty China are encapsulated in the exceptional stone carvings.’
• Work on the sculpture in these caves continued over a 150 year period during the Chinese Middle Ages.
