Added to Unesco's World Heritage List in 2010 and reopened in 2012, Hanoi's Imperial Citadel was the hub of Vietnamese military power for over 1000 years. Ongoing archaeological digs of ancient palaces, grandiose pavilions and imperial gates are complemented by fascinating military command bunkers from the American War – complete with maps and 1960s communications equipment – used by the legendary Vietnamese General Vo Nguyen Giap.
The leafy grounds are also an easygoing and quiet antidote to Hanoi's bustle.
