The turtles in the shrine's pond belong to a critically endangered species known as the Black Softshell Turtle (Nilssonia nigricans).
Zoologists once considered these turtles extinct in the wild, making the population in the pond one of the few remaining examples of the species.
The pond is locally forbidden to fish in, as the turtles are considered sacred by the resident community.
The shrine structure underwent a significant renovation in the early 20th century, though portions of the older Mughal-style brickwork remain visible.
The site is often referred to locally as 'Bostami's Mazar', despite the historical consensus that Bayezid Bostami lived and died in Iran.
The shrine of the 9th-century Persian Sufi mystic Bayezid Bostami is located on a hill in the Nasirabad area of Chittagong. While historically associated with the saint, local tradition suggests he may not have visited the region, but rather that the site serves as a memorial. The complex is most famous for its large pond, known as the Mazar Pukur, which is inhabited by hundreds of black softshell turtles. These turtles are locally believed to be the descendants of djinn or evil spirits transformed by the saint. The site features a historic mosque built during the Mughal period, reflecting the architectural influence of that era. The surrounding area includes a terraced garden layout offering views over the lower elevation of the hill. The shrine remains an active site of pilgrimage for both Sufi practitioners and tourists interested in local folklore. The proximity of the pond and the hillside location create a distinct micro-ecosystem within the urban Chittagong landscape.

Bring a small amount of puffed rice or bananas if you wish to feed the turtles, as this is the standard offering allowed by the caretakers.
Visit the hilltop terrace behind the main complex for a clear view of the surrounding Nasirabad hills.
Keep a safe distance from the pond edge, as the banks can be slippery and are not heavily fenced.
Do not attempt to touch or climb over the railing to interact directly with the turtles in the water.
Dress modestly, covering shoulders and knees; remove shoes before entering the inner shrine area; maintain a quiet demeanor.
