The EFEO center in Hanoi, in its role as a scientific advisor, collaborated with No. 1 Center of National Archives to organize an exhibition on the history of the Long Biên Bridge (formerly the Doumer Bridge) on the occasion of the 120th anniversary of its inauguration.
The exhibition presents to the public around one hundred archival documents dating from 1898 to 1975, many of which are being made public for the first time, along with numerous documents provided by the French National Overseas Archives (ANOM).
