Ālī Qāpū is a grand palace in Isfahan, Iran. It is located on the western side of the Naqsh-e Jahan Square opposite to Sheikh lotf allah mosque, and had been originally designed as a vast portal. It is forty-eight meters high and there are seven floors, each accessible by a difficult spiral staircase. In the sixth floor music room, deep circular niches are found in the walls, having not only aesthetic value, but also acoustic.
The name Ālī Qāpū, from Arabic Ālī, “Imperial or Great”, and Turkic Qāpū meaning “gate”, was given to this place as it was right at the entrance to the Safavid palaces which stretched from the Maidan Naqsh-i-Jahan to the Chahār Bāgh Boulevard. The building, another wonderful Safavid edifice, was built by decree of Shah Abbas the Great in the early seventeenth century. It was here that the great monarch used to entertain noble visitors, and foreign ambassadors. Shah Abbas, here for the first time celebrated the Nowruz (New Year’s Day) of 1006 AH / 1597 C.E.
Ālī Qāpū is rich in naturalistic wall paintings by Reza Abbassi, the court painter of Shah Abbas I, and his pupils. There are floral, animal, and bird motifs. The highly ornamented doors and windows of the palace have almost all been pillaged at times of social anarchy. Only one window on the third floor has escaped the ravages of time.
The chancellery was stationed on the first floor. On the sixth, the royal reception and banquets were held. The largest rooms are found on this floor. The stucco decoration of the banquet hall abounds in motif of various vessels and cups. The sixth floor was popularly called (the music room).
