Babazhi Khatun Mausoleum, Medieval mausoleum in Aisha Bibi, Kazakhstan.

Babazhi Khatun Mausoleum is a medieval brick tomb in Jambyl Province, Kazakhstan, standing a few steps from the Aisha Bibi Mausoleum. The structure shows an umbrella-shaped ribbed dome resting on a square base.

Construction took place between the 11th and 12th centuries as a burial site for Babaji Khatun, who according to tradition protected the nearby monument. The tomb survived through the centuries as a place of remembrance for this protector figure.

Babaji Khatun was Aisha Bibi's companion who became guardian of her mausoleum and was buried 20 steps away. The parapet of the main facade carries a fragmentary Arabic inscription: "This is the tomb called Babaji Khatun… its builder…". The legend of Aisha Bibi survives in 28 versions.

The tomb lies near Taraz city and remains accessible to visitors throughout the year. A visit takes about an hour and combines well with the adjacent monument.

The Arabic inscription on the main facade's parapet survives only in fragments: "This is the tomb called Babaji Khatun… Its builder…". The name of the architect is lost, and the sources record no builder. The original 16-ribbed conical dome also collapsed; the present roof was rebuilt in 1981 to a design by the Kazproyektrestavratsiya institute, and further work in 2002 strengthened the foundations.
