The oval-shaped, slightly cusped Tusha Hiti step-well was commissioned in 1647 by King Siddhinarasimha Malla, probably to perform ritual ablutions. The fountain is furnished with a gilt bronze spout supporting an image of Laksmi-Narayan on Garuda. Its retaining walls are divided into registers of niches, each of which is fitted with a tantric divinity carved in stone or gilt metal. A miniature stone replicaof the Krishna Mandir sits on its main axis, and a protective serpent encircles the brink.
