Cookernag Achabal Verinag spring which is in Verinag town, issues from a high scarp of a mountain spur, and is considered the source of the Jhelum river. It is situated at the bottom of a hill covered by pine trees and evergreen plants. Verinag spring was originally an irregular and shapeless pond, and water, oozing out from different places in it and spread about and formed a little marsh. Emperor Jahangir, whose artistic taste for polishing the beauty of nature is well known, saw this and at once determined to improve it. He built the octagonal tank of sculptured stones round it, so that all water was collected therein, for which carvers were brought from Iran. A garden was also built by Jahangir next to this natural spring which is of pre-Islamic religious significance. The construction date of the octagonal tank and the garden is 1029 Hijri or 1620 A.D, during the 15th year of the Jahangir's reign, which is duly inscribed on a stone slab built into the southern wall of the spring. Seven years later, Jahangir's son Shah Jahan, who was no less a lover of natural beauty, constructed cascades and aqueducts in straight lines through and around the fine garden which he, in order to enhance further the beauty of the place laid out in front of the spring.
