Explain how the fortification and roads …

(a) Fortification : (i) The different parts of the city of Vijayanagara were enclosed with the great fortress walls. There were seven lines of forts. These encircled not only the city of Vijayanagara but also its agricultural land and forests. The outermost wall linked the hills surrounding the city. This wall was built with wedge shaped blocks of stone. They fixed well into each other and had no use of mortar or cementing agent. The inner portion of the walls was of earth packed with rubble.

(ii) This fortification enclosed agricultural tracts like cultivated fields, gardens and forests. The modern archaeologists have found an evidence of an agricultural tract between the sacred centre and the urban core. To irrigate this tract, there was an elaborate canal system which drew water from the Tungabhadra. The agricultural tracts were incorporated within the fortified area with a purpose. In the medieval periods, sieges were laid to starve the defenders into submission. These sieges could last even for months and years. So the rulers built large granaries within fortified areas. So the rulers of Vijayanagara adopted an elaborate strategy to protect their agricultural belt.

(iii) However a second line of fortification surrounded the inner core of the urban complex. A third line of fortification went round the royal centre. There were well guarded gates to enter the fort. These gates led to the major roads. They had distinctive architectural features. There was an arch on the gateway and a dome over the gate.

(b) Roads : The roads linked different parts of the city of Vijayanagara. They also led out of the city. They went through the whole valley. They avoided rocky terrain. Many important roads started from temple gateways. They were lined by bazaars.
