Baoli is a water well. The Mirza Ali Jan’s Baoli, found to the northwest of Narnaul, was built by Mirza Ali Jan, the Nawab of Narnaul during Akbar’s reign. The water well is surrounded by a Chhotta Bara Talaab (small and big ponds).
The main building is shaped like a huge arched gateway and topped by a Takht (Throne) and a Chhatri (Umbrella). Eight pillars support the decorated chhatri. Steps from the pillars lead down to the well.
