Cardinal Donald Wuerl, archbishop of Washington, celebrates the "Mass of Remembrance" at the Basilica of the National Shrine.
In Northeast, the National Shrine of the Immaculate Conception was the setting for a Mass of Remembrance to honor the victims and survivors of the earthquake in Haiti one year later.
American-Haitians and many others all gathered Wednesday at the national shrine to remember the victims and pray for the survivors.
Cardinal Donald Wuerl, archbishop of Washington, was chief celebrant for the mass.
"Haitians do no stand alone. In that solidarity of faith, hope and in love in this nation, and in nations across the world, there are manifestations of that support as that spriit of Haiti faces the future, and the rebuilding of a nation," he says.
Refugees International states approximately 1.3 million Haitians are still without permanent shelter, and living in displacement camps scattered across island.
Marie Charl lives in D.C., but says her heart is in Haiti.
"I lost my best friend and other relatives. I still have relatives back there but they're OK, but as you know it's tough for everyone," Charl says.
Recent figures reveal more that 300,000 Haitians perished in the quake one year ago.
