Indraprastha:

Vishwakarma also built the town of Indraprastha for the Pandavas. The Mahabharata has it that King Dhritrashtra offered a piece of land called 'Khaandavprastha' to the Pandavas for living. Yudhishtir obeyed his uncle's order and went to live in Khaandavprastha with the Pandava brothers. Later, Lord Krishna invited Vishwakarma to build a capital for the Pandavas on this land, which he renamed 'Indraprastha'.

Legends tell us about the architectural marvel and beauty of Indraprastha. Floors of the palace were so well done that they had a reflection like that of water, and the pools and ponds inside the palace gave the illusion of a flat surface with no water in them.

After the palace was built, the Pandavas invited the Kauravas, and Duryodhan and his brothers went to visit Indraprastha. Not knowing the wonders of the palace, Duryodhan was flummoxed by the floors and the pools, and fell into one of the ponds. The Pandava wife Draupadi, who witnessed this scene, had a good laugh! She retorted, hinting at Duryodhan's father (the blind king Dhritrashtra) "the son of a blind man is bound to be blind." This remark of Draupadi annoyed Duryodhan so much that later on it became a major cause for the great war of Kurukshetra described in the Mahabharata and theBhagavad Gita.
