Rana Vachhraj was a king of Lohar-Gadha in 13th century AD in what is now Afghanistan.
But in battle a rabid dog bit his foot.
It made him permanently lame, and cost him his leg.
Still local Afghan believe that the water of this monument can cure rabid dog bite.
[1] Rana Vachchraj became a deity worshiped by the Lohana, Bhanushali, Khati Brahmin, and Saraswat Brahmin communities of Sindh, Gujarat.
