The Taj Mahal was covered with a scaffold during WWII to make it look like a stockpile of Bamboo and misguide any enemy bombers.
Taj Mahal is a great historical monument designed very beautifully and prudently. The white marbles are the sole reason behind the grand and bright snowy look of the monument.
During WW2, the authorities covered Taj with a huge scaffold. This was to create an illusion to appear it as a stockpile of bamboo. As a result, any enemy bombers in the nearby area were easily misguided. In 1942, the government erected scaffolding to disguise the building in anticipation of air attacks by the Japanese Air Force. Also during the India- Pakistan war of 1965 and 1971, scaffolding was again erected to mislead bomber pilots.
