Short answers, pulled from the story.
The Verinag spring was constructed in the year 1620 during the 15th year of Jahangir's reign. The southern wall inscription dated 1029 Hijri records this moment of transformation when the emperor ordered the construction of an octagonal stone basin to contain the waters.
Jahangir's wish to be buried within the Verinag garden was never realized because his wife Nur Jahan chose to disobey his final instructions. The emperor's body was laid to rest elsewhere, leaving the garden as a monument to his unfulfilled longing.
The name Verinag is derived from the Sanskrit words Virah meaning to go back and Nag meaning water spring. This name commemorates the event where the goddess Vitasta found the god Shiva already present at the spring and was forced to return to rise from a spring about a mile to the north-west known as Vithavatur.
Shah Jahan constructed cascades and aqueducts in straight lines through and around the garden to enhance its beauty and functionality. The western wall inscription dated 1037 Hijri records this addition stating that the aqueduct had issued from the heavenly spring.
The source of the Verinag spring is located at the exact center almost 50 feet underwater from where the water continuously rises and flows into the gardens facing the spring. The water flows from the spring into the octagonal pool then down a 305-meter-long canal to the Jhelum River.
The Verinag garden is recognized by the Archaeological Survey of India as a Monument of National Importance. The garden retains its original charm and beauty with the octagonal pool and the surrounding colonnade still intact despite alterations by time and human activity.
