A plan to restore the oldest structure on the National Mall, a 178-year-old Lockkeeper's House from Washington's old canal system, is moving closer to reality with a major gift Tuesday.

American Express is making a $1 million grant to preserve and restore the structure as an education space for the National Mall's visitors, according to officials with the nonprofit Trust for the National Mall. The project is part of a larger rehabilitation planned for part of the mall known as Constitution Gardens that would create a new lakeside garden and restaurant.
