Short answers, pulled from the story.
Asif Khan, the elder brother of Empress Nur Jahan and Prime Minister to Emperor Jahangir, commissioned the construction of Nishat Bagh in 1633. He designed the garden on the eastern bank of Dal Lake with the Zabarwan Mountains as a backdrop.
Emperor Shah Jahan ordered the water supply to be cut off from Nishat Bagh because Asif Khan did not gift him the property after Shah Jahan expressed his delight at the garden's grandeur. This refusal wounded the Emperor's pride and led to the garden being left deserted.
Nishat Bagh features twelve terraces, each representing one of the Zodiacal signs. The layout adapts to the steep hillside of the Kashmir Valley rather than following the traditional square Chahar Bagh design.
The spring that provides water to Nishat Bagh is called the Gopi Thirst. This clear water source flows through the twelve terraces to create the cascading effect and irrigate the chinar and cypress trees.
The tomb of Mughal Princess Zuhra Begum is located within the Nishat Bagh garden. She was the daughter of Emperor Alamgir II and granddaughter of Emperor Jahandar Shah.
