Ali Qapu (from Ottoman Turkish: Âli Qapı, meaning “High Porte”), built at the very end of the 16th century as a residence for Shah Abbas I, is a grand palace in Isfahan. It is located on the western side of the Naqsh-e Jahan Square, opposite to Sheikh Lotfollah Mosque, and had been originally designed as a vast portal. Ali Qapu is actually a pavilion and the entrance to the royal quarters, which stretched from Naqsh-e Jahan Square to the Chahar Bagh Boulevard. Some say the palace’s name is actually Ali’s Gate’ because when Shah Abbas I replaced the door of the Imam Ali (PBUH) (599-661) shrine in Najaf with a new silver one, he brought back its old door and installed it in Ali Qapu Palace. According to some accounts, the original structure was a simple Timurid (1370–1507) one which was expanded by Shah Abbas I. It is said that after celebrating his first Nowruz (Persian New Year) in the palace in 1597, Shah Abbas decided to make it his permanent residence and had the palace modified accordingly. Master miniature painter Reza Abbasi (1565-1635) was commissioned to decorate the interior of the building. On the upper floor, “Music Hall” is definitely worth the climb. Deep circular niches are found in the walls of this room, having not only aesthetic value, but also acoustic. The stucco ceiling is riddled with the shapes of vases and other household utensils cut to enhance the acoustics. This distinctive craftsmanship, considered by some to be one of the finest examples of secular Persian art, extends to the walls. The ceiling of the music room has cut out stucco decorations of vases and goblets which served to enhance the sound of music played for the King. With a height of 48 meters.
