Sati's upper teeth fell on this place.
Adi Sankaracharya was believed to have installed "Sri Chakram at the temple, which is not available now. The temple is declared as a Heritage site and is under the control of ASI. The temple trust of Srisilam has adopted the Jogulamba temple to ensure regular conduct of rituals.
Alampur was ruled by Shatavahana Ishvakus of Nagarjunakonda, Badami Chalukyas, Rashtrakutas, Kalyani Chalukyas, Kakatiyas, Vijaynagara Empire and Qutb Shahis of Golconda.
Alampur was earlier known as Halampuram, Hamalpuram and Amalapuram. As per the inscription dating back to 1101 AD belonging to Western Chalukya, Tribhuvanamalla Vikramaditya VI, Alampur is mentioned as Hatampuram.
Jogulamba Devi is considered as Gruha Chandi (Protector of homes). Jogulamba Devi is seated on a corpse. The idol has huge locks of hair with lizard, scorpion, bats and human skull adorning it. These are the indications of evil and signs of deterioration of a house. Lizard is the primary indication that a house has started deteriorating. When the lizards become uncontrollable, scorpions start entering the house, which is even worse. The next level would be the entry of bats which is an indication of loss of human life in the house. Jogulamba Devi is worshipped for warding off the evil effects of Vaastu Dosha. According to locals, Jogulamba Devi is in Ugra Roopa(highly energetic and hard to worship) and the water pool near the temple makes the atmosphere cool.
The other idols present at the temple are Saptamatrikas (Group of Seven mother- Goddesses, each of whom is a Shakthi or a female counterpart of a god. They are- Brahmani, Maheshvari, Kaumari, Vaishnavi, Varahi, Indrani, and Chamunda, or Yami) Vigneshwara and Veenapani Veerabadra. New idols of Chandi Mundi are placed at the Jogulamba Temple, while the original idols are left behind at Bala Brahmeshwara Swamy temple. The temple also has a Yagnashala, a rest house and a pond. The temple attracts a large number of pilgrims from across the country during festivals like Shivratri and Navratri.
Alampur is also famous for Maharishi Jamadagni's ashram. Maharishi Jamadagni along with his wife, Renuka and four sons was staying in Alampur worshipping Bala Braheshwara Swamy and Jogulamba Devi. Renuka Mata, with her power would regularly make pot with sand and bring water from River Tungabhadra. One day, she saw the King of Gandharva enjoying himself while having a bath in the River with his wives. She immediately felt that pleasures or enjoyment comes from materialistic wealth and not from worshipping God. The very next moment, she lost her divine power of making pots from sand. On reaching home without water, Maharishi Jamadagni wanted to know the reason. Renuka Mata explained the incident and admitted her sinful thoughts. Maharishi Jamadagni got enraged, and asked his four sons to kill Renuka. While three sons refused to kill, the fourth son, Parushuram killed his mother by cutting off her head with his axe. Maharishi Jamadagni was extremely happy and bestowed a boon. Parushuram asked his father to restore life to his mother. Then Jamadagni revived Renuka to life.
The head of Renuka Mata became Ekaveera Devi and the headless portion of the body is worshipped as Bhudevi. Ekaveera Devi symbolises Maya Rupa (materialistic thoughts) and Bhudevi symbolises Matru Rupa(Mother). Many believe that Ekaveera Devi manifested herself as goddess Yellamama in Undavelli village near Alampur, while the temple of Bhudevi is present in the Bala Braheswara Swamy temple.
It is stated that Brahma performed a great penance at this place for propitiating Ishwar by installing and worshipping a Rasalinga. Hence the deity is called Brahmeswara.
