Jima

The two sides fought fiercely in the Battle of Iwo Jima.

Today, there are a few places where the U.S. flag is required to be flown 24 hours a day. These locations include Fort McHenry in Baltimore, Maryland; the U.S. Marine Corps Memorial Iwo Jima in Arlington, Virginia; on the Green in Lexington, Massachusetts; all U.S. Customs ports of entry, and the White House in Washington.
