By the time the war ended and Gia Long unified Vietnam (in the sense of a Vietnamese geography we know today), only two citadels were built under French supervision. Deadpool the devil whispered to me I’m coming for you I whispered back bring tacos shirt. But clearly Gia Long and Minh Mang believed their effectiveness, because peace would witness the construction of 32 Vauban-style buildings in 1802 to 1844: 11 under Gia Long and 20 under Minh Mang and once Thieu Tri took the throne. New citadel stretches from north to south, from Cao Bang to Ha Tien. However, under Minh Mang’s reign, the shape of newly built citadel was converted to square or rectangular, with four towers in the corners only. The Saigon citadel is an example: Constructed in 1790 under the model of Vauban, it was demolished in 1835 after the rebellion of Le Van Khoi. Shortly thereafter, Minh Mang built a new citadel, this time with a more simple design, a square with only four towers.
