آرامگاه زمرد خاتون

Zumurrud Khatun, a Turkish-born concubine of the Abbasid caliph al-Mustadi (r. 1170-1180), was the mother of his successor al-Nasir li-Din Allah (r. 1180-1225)¹. As the caliph’s mother she made the pilgrimage in 1190, paying for wells, pools and lodges in Mecca and Medina¹. Near the grave of the Sufi Ma'ruf al-Karkhi, on Baghdad’s west bank, she built a tomb for herself; the chronicles also mention a library, a Shafi'i madrasa, and a ribat and a mosque where Ibn al-Jawzi preached¹. She died in early 1203 and was carried across the Tigris in procession to be buried there¹. Her grandson Abu’l-Hasan 'Ali, al-Nasir’s heir, was buried beside her in 1216¹.

The building identified with her tomb stands in a large cemetery on the west bank, about 250 m south-west of Ma'ruf al-Karkhi’s shrine^1,2. In 1131 AH (1719) the Ottoman governor Hasan Pasha buried his wife Ayşe there and repaired it¹. Baghdadis long called it the tomb of Sitt Zubayda, wife of Harun al-Rashid, yet Zubayda died in 831 and was buried near Kadhimiya, about 6 km to the north^1,2. Mustafa Jawad’s 1947 study led to the accepted attribution to Zumurrud Khatun, but Dündar urges caution: it rests on 13th-century chronicles, and no source between then and 1947 names the building as her tomb¹.

The tomb is an octagon built entirely of brick, 5.10 m a side and 3.80 m high, entered on the north-east through a rectangular hall added later¹. Above the original round-arched door is the empty base of a lost inscription, and a stair of thirty steps inside the wall leads to the roof¹. Brick frames divide each outer face into four panels: the lower two hold deep pointed-arch niches and the upper two carry patterned brickwork with plant motifs, under a band of zigzag ornament¹.

Three tiers of muqarnas squinches turn the octagon into a sixteen-sided base for the conical dome, which rises 12.30 m above the ground, with twelve tiers of cells inside and nine outside¹. Archnet compares it with the tomb of Imam Dur near Samarra². Of eleven muqarnas-domed tombs in Iraq, Iran and Syria discussed by Yasser Tabbaa, only this one and the tomb of Sitt Zaynab at Sinjar were built for women¹. With the similar tomb of 'Umar al-Suhrawardi (d. 1234) on the east bank, it is one of the few Abbasid-period buildings left in Baghdad¹.

The burial chamber has no windows in its walls, only a faint mihrab niche on the south side¹. Daylight enters through three pointed windows in the fourth tier of the dome, facing east, west and south, and through 120 small openings in the muqarnas cells: sixteen to a tier from the fifth to the tenth tier, eight in each of the two tiers above, and eight in the star at the apex¹. Dündar likens the effect to a dark night lit by the moon and stars¹.
