Description The Matrimandir is an edifice of spiritual significance for practitioners of Integral yoga, situated at the centre of Auroville initiated by The Mother of the Sri Aurobindo Ashram. It is called soul of the city and is situated in a large open space called Peace. Matrimandir does not belong to any particular religion or section. The Geodesic dome is covered by golden discs and reflects sunlight, which gives the structure its characteristic radiance. Inside this central dome is a meditation hall known as the inner chamber - this contains the largest optically-perfect glass globe in the world.
