Read the passage and answer the question:

Before we examine the different parts of the city in detail, let us look at what enclosed them all-the great fortress walls. Abdur Razzaq, an ambassador sent by the ruler of Persia to Calicut (present-day Kozhikode) in the fifteenth century, was greatly impressed by the fortifications, and mentioned seven lines of forts. These encircled not only the city but also its agricultural hinterland and forests.

The outermost wall linked the hills surrounding the city. The massive masonry construction was slightly tapered. No mortar or cementing agent was employed anywhere in the construction. The stone blocks were wedge shaped, which held them in place, and the inner portion of the walls was of earth packed with rubble. Square or rectangular bastions projected outwards.

What was most significant about this fortification is that it enclosed agricultural tracts. Abdur Razzaq noted that "between the first, second and the third walls, there are cultivated fields, gardens and houses."
