to withstand catapults and other artillery. By the mid-12th century, the galleries were filled in, and the wall was greatly strengthened. A secondary, smaller wall was built in front of the Soltangala's main wall, and finally the medieval city's suburbs—known today as Isgendergala—were enclosed by a wall. The three walls held off the Mongol army for at least one of its offensives, before ultimately succumbing in 1221. Many ceramics have been recovered from the Abbasid and Seljuk eras, primarily from , the city walls of Soltangala, and the Shahryar Ark. The ware was primarily late Abbasid and consisted primarily of red slip-painted bowls with geometric designs. The pottery recovered from the Sultan Gala walls is dominated by 11th to 12th-century colour-splashed yellow and green pottery, similar to contemporary styles common in Nishapur. Turquoise and black bowls were discovered in the Shahryar Ark palace, as well as a deposit of Mongol-style pottery, perhaps related to the city's unsuccessful re-foundation under the Il-khans. Also from this era, is a ceramic mask used for decorating walls found among the ruins of what is believed—not without controversy—to be a Mongol-built Buddhist temple in the southern suburbs of Sultan Gala. Shaim Kala Shaim Kala was built in the 7th AD. Shaim Kala was a self-contained walled city intended to relieve over-crowding, and to deal with the religious and political discontent of the newly arrived peoples.
