The center of the city with many of the tourist attractions is known as District 1. Stretching away from the promenade overlooking the river with its numerous ferries and ocean-going ships are several of the wide boulevards that put most of the major attractions within an easy walk or cyclo ride from the major hotels in this area (Rex Hotel, Renaissance Riverside Hotel Saigon and the Saigon Prince Hotel). Many of the more interesting museums are nearby, including the former Presidential Palace, now known as Reunification Palace and famous for the 1975 pictures of the tanks crashing through the gates. Across the street is the Museum of Ho Chi Minh City which along with the History Museum near the City Zoo will entertain you with the unique art form of Vietnamese water puppets.
