This is the principal shrine of Goddess Amba, who has been worshiped since the pre-Vedic period. Made of white marble with gold cones, the temple was originally built by Nagar Brahmins. The temple is surrounded by an open square called chachar chowk where ceremonial sacrifices called havans are performed.
The inner sanctum of the temple has silver-plated doors. There is a gokh, or niche, in the wall on which is fixed an inscription of the Viso Yantra, a Vedic text on sacred geometry, which is the main focus of worship. There is no idol of the goddess, perhaps because the temple is so ancient that it predates idol-worship, but the priests decorate the upper portion of the gokh in such a way that it looks like an idol of a goddess from a distance.
