O Hampi had a good port as it was near to the sea so it would be good for rulers there for earning revenue and increasing the economy. Traders visited Hampi to pursuit trade activities. The walls of Hampi were constructed and fortified well. The technique used, ensured that no cementing agent or motor was used and hence it was interlocked and held together firmly. The building's inside this royal complex had magnificent domes and arches. ---Hope this helps--BakuxxxChan
