In the heart of the Vijayanagara Empire, a remarkable system of fortifications and roads was established, reflecting both military might and economic strategy. The city was encircled by a series of fortification walls—seven layers, as noted by the Persian ambassador Abdur Razzaq—designed not only to protect the city but also to safeguard the agricultural lands within. The walls were constructed with precision, without any mortar, using wedge-shaped stones that held firm. The fortifications included agricultural tracts, ensuring the city remained self-sufficient even during sieges. Key roads connected vital areas within the city and provided links to the outside world, facilitating trade and movement. They were strategically placed to maximize accessibility, with bazaars often lining these streets. The influence of Indo-Islamic architectural styles was apparent in the gateway designs, marked by their arches and domes. Overall, the fortifications and roads exemplified the empire's advanced planning and integration of military and economic priorities.
