What do these numbers mean?

A height of 48.5 m is about 16 storeys at 3 m each.

Calculation

48.5 m ÷ 3 m = 16.17 ≈ 16

The base area is about 29,000 m².

Calculation

188 m × 156 m = 29,328 m²

That is about 4.1 football fields measuring 105 m × 68 m.

Calculation

29,328 m² ÷ (105 m × 68 m) = 4.11 ≈ 4.1

Measurement basis

The present-day ruined elevation is scaled uniformly from the maximum preserved height of 48.5 m; its natural width is not stretched to the historic diameter because exterior rings are missing. The top view shows the incomplete surviving rings inside the full 187.75 × 155.6 m historic ellipse.
