Did you know the Flute echoes 5 times inside the Taj Mahal?
The acoustics inside the main dome, which soars to 240 feet, can cause the single note of a flute to echo five times. The meticulously engineered and decorated Taj Mahal required 22 years of labor by 20,000 workers. And more than 1,000 elephants were deployed to carry construction materials. https://www.nationalgeographic.com/travel/article/taj-mahal-1
