Heavy rains damage George Washington's Mount Vernon estate

Heavy rains have caused major damage at George Washington's Mount Vernon estate in northern Virginia.

Mount Vernon CEO Curt Viebranz said about 100 feet of a brick wall located between Washington's iconic mansion and the Potomac River fell over after the estate was hit by more than 5 ½ inches of rain in a single hour Friday evening. A pathway between the mansion and Washington's tomb was also washed out.

Viebranz said no historical buildings were damaged, but the cleanup and repair costs could still total in the seven figures.

He said staff have been working around the clock to make sure the estate stays open for visitors.
