Washington DC Capitol Christmas Tree
There is one spot on the list where the astronomical cost of a Christmas tree does not imply fake limbs, twigs, or leaves. Since 1964, Washington's Capitol has pledged to plant a conifer from its own commissioned tree nursery in front of the White House once it is holiday-ready, replacing the live thing roots.
The massive yet spiky Washington DC Capitol Christmas Tree, which can reach a height of 20 meters, necessitates the use of thousands of lightbulbs to bring out its beauty. Consider the complexities of removing the plant from its current location while ensuring that the roots remain intact, transporting it to the Capitol grounds, and negotiating with the stinging branches, and it's easy to see how costs may soon reach a million dollars. Locals and visitors alike don't mind, of course: the sight is worth the price.
Cost: $1 Million
