Bonalu - Ujjaini Mahankali temple

This temple in Secunderabad was built in 1815 by Suriti Appayya, a resident of Secunderabad. It so happened that he had to move to Ujjain of Madhya Pradesh on military duty and witnessed the death of thousands who succumbed to Cholera in the year 1813. He prayed to the goddess Mahakali of Ujjain and offered an oath that he would build a temple for her at Secunderabad in case cholera came under control. His prayers were answered almost immediately and the disease was successfully contained. He then brought a wooden statue of Kali, and installed it in Secunderabad. This idol came to be known as Ujjaini Mahankali.

Later another idol by name Manikyala Devi was unearthed in a nearby well and was installed next to the former's.

The wooden statue of Mahankali was replaced in 1964 with a stone statue and consecrated.
