In the middle of the town is the Matrimandir, which was conceived by Alfassa as "a symbol of the Divine's answer to man's aspiration for perfection". Silence is maintained inside the Matrimandir to ensure the tranquility of the space, and the entire area surrounding the Matrimandir is called the Peace area. Inside the Matrimandir, a spiraling ramp leads upwards to an air-conditioned chamber of polished white marble referred to as "a place to find one's consciousness".

Matrimandir is equipped with a solar power plant and is surrounded by manicured gardens. When there is no sunlight, the sunray on the globe is replaced by a beam from a solar-powered light.
