The tomb of Emperor Tu Duc was built during his lifetime to be an auxiliary Palace. He spent much time there. This is a large compound which has 60 buildings. There were buildings to house his family, staff and the Civil Mandarins who came with him when he was in residence. He named his compound Van Nien Co (Construction of Eternity) The Mandarins in charge of construction pushed the workers to finish the tomb in 3 years instead of the 6 years that were planned. This angered the workers and Tu Duc's popularity suffered. He changed the name of his compound to Khiem Cung (modest tomb).
Tu Duc was a very educated and intellectual man who wrote over 600 essays.
Please excuse the dates on the photos. I turned the date on accidentally but did not set it.
