What white house room is named after a foreign country?
No one named it the White House, but it happened after the burn marks were covered by white paint after the British burned it in 1812. To paint a house in the 1800's was very expensive and a whole house painted white would have stood out in undeveloped Washington DC. People began to refer to it as the "White House" so it came in general usage.
The White House has not always been white. In the War of 1812, it was set of fire, and it burned. I believe it was the French who did this. Although it didn't get completely destroyed, the exterior of the building was badly burned, and, therefore, the building was discolored. So, they had it painted white, which is how we get the name for the White House.
