Liang Sicheng
The structure and ornamentation have remained the same since the pagoda was built, but the 1976 Tangshan earthquake caused the original pearl-shaped steeple of the pagoda to break off and fall. It has since been restored. The temple grounds surrounding the pagoda have also been renovated and rebuilt several times over the course of the Ming and Qing dynasties. The architectural historian Liang Sicheng (1901–1972)—known for discovering and documenting the oldest existent wooden structures still standing in China—lauded the Pagoda of Tianning Temple as a pristine architectural design of antiquity.
