Taj Mahal, one of India’s most well-known monuments, is the “World’s Seven Wonders of the World”. It is a huge white marble building and it is located in India. All bell tower, minarets, ponds, etc.,  are with pure white marble building, with glass, agate mosaic, with high artistic value. It’s maybe hard to keep clean and beauty because of white color. However, It’s really a brilliant building for me.
