The Chaurasi Khambon ki Chhatri is an 84-pillared cenotaph built in honour of a wet-nurse of Rao Raja Anirudh Singh in the 18th century. Located a short distance from the town centre, it is a beautiful and unexpected structure: a multi-tiered pavilion with intricately carved pillars, arches, and a small Shiva shrine at its base.
The site is relatively off the tourist trail compared to the palace and step-wells, which means you may have it to yourself. The carving quality is high and the setting, near a dry riverbed with views back toward the fort, is genuinely atmospheric. Worth combining with a visit to nearby Nawal Sagar Lake and the surrounding ghats.
