We visited the Museum of Vietnamese History in the morning and saw a short water puppet show.
We then went to Independence Palace (also known as Reunification Palace), which was the site of the end of the Vietnam War when Saigon was captured by the North Vietnamese Army and the Viet Cong in 1975.
The current palace was was built in the the 1960s and since it was overtaken in 1975, not much has changed externally or internally.
The basement bunker was really interesting as it contains lots of secret tunnels and a war room and old telecommunications equipment from that era.
