Mehrangarh Fort, Jodhpur, Rajasthan, one of the largest and most impressive forts in India.
It’s quite a hike to make your way from the old town, up through maze of walls and gateways, to the top of the fort. It is worth remembering, that some who attempted this jaunt ended up impaled on spikes, showered with boiling oil, shot with arrows, and / or hacked, cleaved or decapitated.
