Warangal fort, India is the case study. Impact craters are catastrophic natural events. Circular rings are associated. Some have mono others have dual. Principles and mechanics of ring formation are discussed and a unique ‘Cone Concept’ is hypothecated. Anecdotal evidences are factored in multidisciplinary method. A shock wave divert is designed based on ‘cone concept’ and gem formation. Gem formation is also discussed. Impact preceded evolution of Homosapiens who may have occupied it as most, best, safe, preferred habitat. Useful in civil engineering, heritage studies and Smart Cities. A first time, original report.
