Đồng Hới
The city was close to the Vietnamese DMZ, and it was in North Vietnam during the Vietnam War. Since it was so close to the DMZ, it was important for the North Vietnamese. For this reason, the city was heavily bombed by the US Air Force. There is a cathedral called the Tam Toa Church that was bombed during the war. Tam Toa is still ruined today so people could remember the bombing of North Vietnam.
