The Washington Monument will remain closed for repairs until 2014, National Park Services said Monday.
The 555-foot-tall monument has been closed since an earthquake struck the mid-atlantic region near Richmond, Virginia, in August 2011.
The monument usually has 700,000 visitors a year. David Rubenstein, co-founder of the investment firm The Carlyle Group, has donated $7.5 million toward the repair project.
The Washington Monument was built between 1848 and 1884 and has been repairs three time previously, the most recent work done from 1997 to 2000.
