Audience Hall of Apadana
Apadana was the first building constructed and is the most important on the
terrace of Persepolis . It stood architecturally and in the sense of urban planning
as the hub of the terrace. It is an architectural wonder of the ancient world
- its clever construction enabled dimensions without comparison in its time.
The 20 meter (65,5 ft) high columns were the tallest and thinnest that architects
had mastered - and construction-wise, it was a clever feat. In many respects
its construction was a masterpiece of architecture. The architects of Darius
had the courage to raise the height of the columns 1.5 meters (4,9ft) higher
than those of the Temple of Artemisia at Ephesus and to refine the tapering
of the diameter to 1:12. The distance between the columns , in comparison to
the 5.9 meters (19,4ft) at the Temple of Artemisia, was stretched to an astounding
8.65 meters (28,4 ft). This unique wide-spacing resulted in a festive spacious
atmosphere in the Apadana. The effect of which was only possible by combining
stone columns and wood ceiling beams.
