 Such a gate with spikes can be seen on the Shaniwarwada fort, Pune.The walls of the forts were often looked higher from the outside than the inside as the forts made use of the natural rock formations on hills.This not only gave an illusion of greater height but also lead to the lower walls of the fort to be entirely made up of natural rock providing almost a perfect defense against the use of a battering ram or elephants to tear down the walls.
