Nestled in the fascinating surroundings of the historical Mehrauli Area of South Delhi, Chhattarpur, a small village of yore, now is known more by the divine pulsations of Shree Adya Katyayani Shaktipeeth Mandir. Founded in the Nineteen seventies by Sant Shree Nagpal Baba, the place has now become a pilgrimage Centre of renown, visited by devotees from all parts of the country, nay the world. The Mandir precincts offer to the visitors exquisite architecture, a blend of North and South. The enthralling statues of the deities like Maa Katyayani, Maa Mahishasurmardini, Ram-Darbar, Radha-Krishna, Shiv-Parvati, Laxmiji, Ganeshji, Hanumanji etc make one standstill in adoration with extreme admiration of the presence of the divine which is more eloquent than silent. The special celebrations during Navratras, Mahashivratri and Janmashtami make the temple abuzz with religious fervour to the delight of the devotees congregating in hundreds and thousands. The lungar Prasad distributed in both the Navratras to approximately a lakh visitors daily is a rare sight to see and believe.
Shree Adya Katyayani Shaktipeeth Mandir Trust right since the days of Baba Nagpalji is controlling the affairs of the Mandir and running a number of religious and social programmes benefitting cross sections of the Society.

The Mandir, spread over an area of approximately 70 acres, has a number of structures, separate as well as combined, dedicated to each deity with large halls for congregation of devotees. The Shiv Mandir, Ram Mandir, Maa Katyayani Mandir, Maa Mahishasurmaridini Mandir, Maa Ashtabhuji Mandir, Hanuman Mandir, Laxmi Vinayak Mandir, Jharpeer Mandir, Markandeya Mandapam, Baba Ki Samadhi, Nageshwar Mandir, the Trident (Trishul), 101 feet high Hanuman Murti etc are special attractions for the devotees and even common visitors.

Apart from the Mandirs, Shree Adya Katyayani Shaktipeeth Mandir Trust is also engaged in social services in the form of Medical & Diagnostic Centre, School, Gurukul, Vocational Training Centre etc. Offerings to a number of institutions like Kushtrog Ashram, Dargah of Nizamuddin Aulia, Shrines at Bharthari etc are sent regularly by the Trust keeping in line with the tradition established by Babaji who was a humanist to the core. The Trust is committed to pursue the ideals preached and practised by Baba Nagpal himself and the increasing popularity of the Mandir day in and day out has kept it inspired to work more and more in the interest of devotees and public at large.
