Two additional underground tunnels at Thang Long Imperial Citadel in Hanoi will be reconstructed and connected with the revolutionary relic system to open to the public in 2019.

An underground tunnel at the Thang Long Imperial Citadel

The information was released at a forum held at the Citadel last week.

The items include tunnel 59, which was an office serving the General Staff, and tunnel 66, which was used to encipher and secure orders by the General Command to the battlefields during the resistance war against the US.

They were designed to withstand regular attacks by bombs, heavy missiles and even nuclear and chemical wars. Each shelter has a total area of 20 square metres and consists of two compartments.

At the forum, historical witnesses recalled the unforgettable memories about their works at the two tunnels, notably during the tough 12 days and nights in late 1972 and the historic Ho Chi Minh Campaign in 1975.

The revolutionary relic site is a part of the Thang Long Imperial Citadel, which was recognised as a world cultural heritage. The introduction of the tunnels to the public will contribute to promoting Vietnam’s historical and revolutionary values to younger generations as well as international friends.
