How'd they do that?!

How'd they build the Taj Mahal? It was built in the 1600's. What architectual skills did they have to build the dome on top? Or get those tiny little points on top of the domes. Or the towers rising on the side. Did they have advanced scaffolding? Did people die building it? I wonder if people know it's a tomb. What does the inside look like? Is is as beautiful as the outside? I always see pictures of the outside, never the inside. Are there altars to pray for the dead inside? Are there candles burning, incense? I went to google and looked up images. Its really pretty inside. Shah Jahan, the emperor of of the Mughal empire, built the Taj Mahal as a tomb for his third wife, Mumtaz Mahal, after her death during childbirth. He was placed on house arrest soon after is completion by his son Aurangzeb, and was buried next to his wife after he died. An elaborate pulley system, and an extremely large scaffolding system was the technology used to build the Taj Mahal. It is named one of the Seven Wonders of the World
