A 30-metre tall Christmas Tree on the border between South and North Korea. Doesn’t look like a Christmas Tree to me, but I like the idea:

South Koreans light giant border Christmas tree

A 30-meter-tall (100-foot-tall) steel Christmas tree with about 30,000 light bulbs, is lit by Christian groups at a mountain peak in Gimpo, South Korea, on Dec. 22. The Christmas tree would be visible by North Koreans living near the Demilitarized Zone that divided the two Koreas.
