RE/Custis - 2/28/02 by Dayna Smith/twp - The Custis-Lee Mansion, aka Arlington House, in Arlington National Cemetery is one of the nation's premier examples of Greek Revival residential architecture. ORG XMIT: 121375 (Dayna Smith/TWP)

A rear wall suffered minor separation from the house, and a significant amount of plaster damage also occurred, said Matt Henderson, acting site manager of the National Park Service managed memorial in Arlington National Cemetery. The wall is not going to fall, according to engineers who have examined the damage, Henderson said, but the back hallway and upstairs have been closed to visitors since the earthquake. The rest of the house remains open.

Henderson said there is no estimate on the cost of repair or how long repairs will take. A major restoration project was already underway when the quake struck.
