The Washington Monument, one of the US capital's most recognizable sights, was to reopen Monday, three years after sustaining damage from a rare earthquake.
The popular tourist attraction is the US capital city's tallest building at 555 feet (170-meters).
The obelisk, built in honor of the first US president, George Washington, was closed after engineers found 150 cracks in the structure following a 5.8-magnitude earthquake in the neighboring state of Virginia in August 2011.
The structure was covered in scaffolding for months on end as the landmark underwent $15 million in repairs, half of which was funded by a private citizen.
"This enduring spirit of public-private partnerships has made it possible for visitors to once again enjoy the Monument and its unmatched view of Washington" said US Secretary of the Interior Sally Jewell said in a statement.
Jewell will attend a reopening ceremony attended by US celebrities, with accompaniment by the United States Navy Band.
Public tours recommence after the ceremony, with tickets available on a first-come, first-served basis, officials said.
The Washington Monument, completed in 1885, is located in the middle of the National Mall, between the Capitol and the Lincoln Memorial.
The 2011 quake rattled a large swathe of the US East Coast, a region not usually prone to earthquakes.
It was centered in Louisa County, northwest of Richmond, and also caused significant damage to Washington's National Cathedral.
