The Ghanshyam Das Birla Sabhagar was established in 1984 by Dr. K.K. Birla. Located under the iconic Radha Krishna Mandir in the heart of Kolkata, the Sabhagar was built as a space to hold primarily religious and philosophical discourses. Since that time, the Sabhagar has grown into an institution promoting arts and culture in Kolkata. Retaining all the charm of old world Kolkata, the Sabhagar today is home to a variety of theatre, musical and dance performances, both classical and contemporary, as well as philosophical and religious lectures and discussions. With flawless acoustics, complete air conditioning, luxurious push back chairs, four green rooms, a music room and a foyer, the Hall hosts a range of corporate events (AGMs, product launches etc.) school events and cultural functions, under the guidance of Shrimati Nandini Nopany. The Sabhagar can accommodate 665 people in the main auditorium. Smaller workshops and seminars can be held in the Library, which can accommodate 40 people and contains a variety of philosophical and religious texts. There is also a Box on the ground floor level that is easily accessible for people who find it difficult to climb stairs.

Founded in 1985 Sanskriti Sagar is a charitable organization that was created to further the mission of the Sabhagar – to promote and provide a platform for the rich culture of Kolkata and West Bengal. A society comprising of over 300 members, Sanskriti Sagar organizes up to 20 different cultural events over the course of the year for the benefit of its many members. These events range from religious lectures to contemporary plays and are intended to appeal to people of varying age groups. Sanskriti Sagar is also engaged in active collaboration with numerous cultural groups around the city and the country in an effort to promote the work of both local and national artists.
