Dinh Hoa ATK (Safety Zone)

Dinh Hoa ATK (An Toan Khu) is a Special National Relic complex in Dinh Hoa District, Thai Nguyen Province, about 100 km north of Hanoi. It served as the revolutionary base and headquarters of the Vietnamese resistance government from 1947 to 1954. Set in forested hills, the site preserves stilt houses, meeting huts, and memorials where key national decisions were made, and is a major historical and patriotic education destination.

Visitors can expect a large forested historical complex spread across several communes centered at Phu Dinh, with restored stilt houses, thatched meeting huts, exhibition houses, monuments and memorial steles set among hills, bamboo forests and streams. Areas to explore include Tin Keo Hut, Khuon Tat, Deo De and the ATK Exhibition House displaying documents, photos and artifacts. The environment is quiet and natural with walking paths, guided tours and viewpoints over the surrounding countryside.

ATK Dinh Hoa was the Safety Zone and headquarters of the resistance government during 1947-1954. It was where President Ho Chi Minh and central agencies lived and worked, and where many important political and military decisions were made. The complex was designated a Special National Relic in 2012 and preserves numerous revolutionary sites including Tin Keo, Khuon Tat and Deo De.

The site is a nationally significant heritage and patriotic education destination, representing the revolutionary history and cultural identity of the Viet Bac region. It is preserved as a memorial complex for visitors to learn about mid-20th century history and is an important cultural landmark for Thai Nguyen Province.
