Kankaria Lake, Artificial lake in Maninagar, India.

Kankaria Lake is an artificial lake in Ahmedabad with a distinctive 34-sided geometric shape. A network of stone steps provides water access from multiple points around the perimeter, and an island with gardens and historical structures occupies the center.

Construction began under Sultan Muizz-ud-Din Muhammad Shah II and was completed in 1451 during the reign of Sultan Qutb-ud-Din Ahmad Shah II, as recorded in an inscription naming it Hauj-e-Qutb. The 34-sided reservoir was dug as a royal bathing tank with a purification system. Collector Borradalle restored it in 1872, and the lakefront was revamped in 2007–2008.

The lake serves as a popular gathering spot for families and couples, especially during sunset hours when residents come for evening walks. The shoreline features parks and small gardens where locals spend time relaxing and socializing.

The lake is easy to explore on foot along the shoreline, with wide paths and plenty of resting spots. Visitors should choose early morning or evening hours to avoid heat and enjoy the best views.

The island garden is called Nagina Wadi, Urdu for "beautiful garden"; the 17th-century traveller Mandelslo described it as a jewel planted by a rich young lady. A bridge originally of 48 stone arches linked it to the bank, and the island holds the Ghattamandal pleasure house.
