From the two remaining sides its distance is apparently about 28 feet.

The present height of the second story, including the rubbish upon its top, is 19 feet; but we may reasonably suppose that the original height was much greater.

The material of which its inner structure is composed, seems to be chiefly (or wholly) partially-burnt brick, of a light red color, laid in a cement composed of lime and ashes.

This central mass is faced with kiln-dried bricks of large size and excellent quality, also laid, except on the north-west face, in lime mortar.

No buttresses and no staircase are traceable on this story; though it is possible that on the south-east side the grand staircase may have run the whole height of both stories.
According to information received by Mr.Taylor from the Arabs of the vicinity, there existed, less than half a century ago, some remains of a third story, on the summit of the rubbish which now crowns the second.
This building is described as a room or chamber, and was probably the actual shrine of the god in whose honor the whole structure was erected.
Mr.Taylor discovered a number of bricks or tiles glazed with a blue enamel, and also a number of large copper nails, at such a height in the rubbish which covers up much of the second story, that he thinks they could only have come from this upper chamber.
