worst fire to strike Windsor Castle in its 900 years. The castle, her official residence and the place where she usually spends her weekends, is the oldest and largest inhabited castle in the world.
"The heat of a single spotlight left too close to a curtain in the monarch’s private chapel was all it took to bring the iconic fortress to its knees," the Mirror reported. Windsor Castle, Queen Elzabeth's favorite residence, is about 30 miles outside London.
The restoration took five years and cost 40 million pounds (almost $65 million at today's exchange rates, not adjusted for inflation). Click here or on the before-and-after image above to see a slideshow of the fire and the restoration, including some stunning interior shots.

In the words of one of my more sympathetic correspondents, it has turned out to be an 'Annus Horribilis'" -- a Latin phrase meaning horrible year that her speech helped make famous.
Today is also Queen Elizabeth's 66th wedding anniversary. She married Prince Philip in 1947.
