On July 21, the People's Committee of Thanh Binh Commune, Da Nang City held a ceremony to receive the provincial-level relic ranking certificate for the Bat Cave scenic spot.

Bat Cave is located in Tien An commune, Tien Phuoc district, Quang Nam (old), now Thanh Binh commune, Da Nang city, and was ranked as a provincial-level relic by the People's Committee of the old Quang Nam province (now Da Nang city).

According to Mr. Duong Duc Lin - Chairman of Thanh Binh Commune People's Committee, although Thanh Binh is a newly established commune, it is a cultural and historical area with hundreds of millions of years of history, a place with strong imprints and evidence of prehistoric culture, Sa Huynh culture, and Cham culture.

Evidence of the natural weathering process on the earth's crust has left behind many breathtakingly beautiful landscapes such as Lo Thung, Bat Cave, O Waterfall - Vin Abyss, and Deo Lieu Waterfall.

Among them, Bat Cave is highly appreciated by geologists for its natural, cultural and historical value, and is likened to a Jurassic Park with fossil formations.

Bat Cave Complex was formed from 530 to 158 million years ago, one of the oldest rock formations in the Quang Nam - Da Nang region.

The rocks of the Kham Duc and Nui Vu formations are metamorphic rocks exposed widely in the Bat Cave scenic spot, clearly shown through their color, foliation, and micro-folding structure.

This is a rare exposure in the tropics because it is entirely exposed bedrock, while in most other places (in Yen Bai , Nghe An and the Central Highlands) bedrock is heavily weathered.

The exposed bedrock of Bat Cave is like a natural museum of geological activity, contributing to clarifying the history of an important geological development stage of the Earth.

Bat Cave has a charming natural landscape. The slate cliffs are very sharply abraded, creating strange, attractive lines like ancient characters on the surface of the cliffs. The rocks are majestic, strong, and have majestic shapes.

During the resistance war against France and the US, Bat Cave was the base of revolutionary organizations of Zone V, the Provincial Party Committee and Tien Phuoc District. This was the place chosen by the QB 150 engineering workshop of Zone V as the base for the production of weapons and ammunition.

Thanks to the abundant source of bat guano in the caves, QB 150 engineering workshop in Zone V exploited it to produce gunpowder, ensuring a source of ammunition for the entire battlefield in Zone V.

Mr. Lin said that Bat Cave has been planned as a destination and is one of the outstanding spots with potential for local eco-tourism development.

Many scientists and artists have come to Bat Cave to research and compose, this is a good sign for the development of tourism activities in the future.
