Former U.S. President Abraham Lincoln’s final resting place in the Oak Ridge Cemetery in Springfield Illinois. Lincoln’s tomb is a National Historic Landmark and it’s estimated that about 350,000 people pay a visit to the site each year. And with the 150th anniversary of the 16th President’s death approaching next year, a massive $700,000 restoration project is underway on the tomb to repair long-standing water damage, according to The State Journal-Register.

From the story:  “Water infiltration has been an ongoing problem at the tomb since it was built in 1869. The flat roof has led to water damage to portions of the ceiling and some of the decorative plaster trim. A lot of the damage was in the rotunda, where the plaster trim and some of the palladium leaf was peeling from the ceiling.

The burial chamber, which has gold leaf on the ceiling, had similar problems.”

The tomb has been closed since December 1, 2013 and expected to reopen this April.
