Forts in India

"Forts are the bedrock of swarajya."

"It is true that the Rigveda does not provide us details of the inner layout of these forts, but surely the text was not meant to be a treatise on Vastusastra. May it be remembered that it is essentially a compilation of prayers to gods and should be looked at as such. All the evidence that it provides regarding the material culture of the then people is only incidental."

"Far away in fortresses of unbaked bricks"

"For Divodasa, him who brought oblations, Indra overthrew A hundred fortresses of stone."

"And, irresistible, be thou a mighty iron fort to us, With hundred walls for man’s defence."

". . . stitch ye [oh gods] the coats of armour, wide and many; make iron forts, secure from all assailants."
