This picture shows Mansagar Lake in the background, with pillars in the foreground.
These pillars belong to an old unfinished building structure in red color stone and is located on Nahargarh hills.The structure doesn’t have a roof. No information regarding purpose etc is available for this structure. However, it is possible that this was a view-point for the Mansagar Lake!
Its a great place to sit, soak in the view and enjoy some peace. Do avoid Sunday, though!
