The magnificent six-story Ali Qapu Palace, constructed at the very end of the sixteenth century as a dwelling for Shah Abbas I, also served as a colossal gateway to the imperial palaces that lie in the parklands beyond. Named for Abbas' hero, the Imam Ali, it was constructed to make an impression and at six stories and 48 metres tall it did. French traveler Sir John Chardin portrayed it as the biggest palace ever constructed in any capital.

The best part of the palace is possibly the elevated patio with its 18 small columns. The terrace gives a magnificent perspective over the plaza and one of the most excellent sights of the Imam Mosque. If you look up, you will notice a gorgeous wooden ceiling with complicated inlay work and uncovered beams, reminiscent of the close by Chehel Sotun Palace. Several of the precious paintings and mosaics that one time decorated the tiny rooms, corridors and staircases were shattered during the Qajar era and since the 1979 revolution. However, some remain in the throne area, which leads off the patio. 

On the upper level, the music room is unquestionably worth the climb. The stucco ceiling is riddled with the figures of vases and other household utensils cut to improve the acoustics. This unique craftsmanship, considered by some people to be one of the supreme examples of worldly Persian art, extends to the walls.
