龙门石窟
One of the major achievements in this direction is the recognition given to the monuments by UNESCO in declaring the Longmen Grottoes a heritage monument, after due evaluation over a period, and inscribing it in the World Heritage List. The recognition is based on Criteria (i), (ii), and (iii): "Criterion (i), the sculptures of the Longmen Grottoes are an outstanding manifestation of human artistic creativity; Criterion (ii) the Longmen Grottoes illustrate the perfection of a long-established art form which was to play a highly significant role in the cultural evolution of this region of Asia; and Criterion (iii), the high cultural level and sophisticated society of Tang Dynasty China is encapsulated in the exceptional stone carvings of the Longmen Grottoes." This also enjoins the Government of China to take adequate steps to preserve the monument in its heritage status according to guidelines issued from time to time after frequent inspections of the site.
