The Washington Monument, an obelisk in the United States capital's National Mall, reopened to visitors on Thursday following the completion of a three-year renovation project.

The special guests at the reopening were first lady Melania Trump and a group of 10-year-old students who helped her ceremonially reopen the 170-meter-high (555-foot-high) structure by cutting a red, white and blue ribbon that encircled it.
