of the French buildings from the nineteenth and early twentieth centuries remain in Hanoi, such as the Grand Opera House, the Presidential Palace, the National Museum of Vietnamese History, and St. Joseph Cathedral. The outsides of these buildings harken back to a previous chapter in Vietnam's history, while the insides are filled with relics of Vietnam's history and culture. Inside the National Museum of Vietnamese History, for example, you'll find antiques and displays that document the thousand years between the tenth century and the twentieth.
