Participants were updated on latest results of an archaeological survey at Trang An and a geographical map of the complex.
According to PhD Ryan Rabett, director of the Trang An Archaeological Project, said that the project examines the impacts of weather, geology and terrain on local livelihoods and vice versa.
Measures to protect Trang An complex were also on table at the event.
Tran Van Tan, head of the Vietnam Institute of Geosciences and Mineral Resources, highlighted that the coordination between local authorities, enterprises and people has produced positive impacts on the preservation of the complex.
Scientific research will reveal the values of the complex in both geological and archaeological spheres, Tan said, adding that this will help raise local awareness of the heritage protection.
Attending the two-day conference, participants are set to visit Trang An eco-tourism site and Moi and Hanh caves where a line-up of archaeological relics were found.
The Trang An Archaeological Project will be carried throughout 2019.
Trang An complex is a World Natural Heritage site and includes Tam Coc-Bich Dong- a series of karst caves and mountain pagodas, the ancient and new Bai Dinh pagoda and the Hoa Lu ancient capital.
The area, dotted with forest, lime mountains, rivers, lakes and dams, covers 12,252 hectares.
