Kyz-Kala, located in the Merv oasis near the city of Bayram Ali, consists of two small fortresses that are significant remnants of the region’s rich history. The larger of the two, known as Greater Kyz-Kala, was a two-story structure. The first floor contained five rooms, accessible via a staircase that descended through an arched corridor. Although only fragments remain, the second floor appears to have also housed five rooms arranged around a central courtyard.
In contrast, the Lesser Kyz-Kala is in a much poorer state of preservation. However, archaeological excavations suggest that both fortresses were constructed following a similar plan. One of the most remarkable features of these structures is their corrugated walls, built from unbaked bricks. Inside the fortress, residential and utility rooms surrounded a central courtyard, providing a design that was well-suited to the steppe environment—cool in summer and warm in winter. The fortress also served as a granary, storing crops, which is why it was capable of withstanding long sieges.
Greater Kyz-Kala was erected over a thousand years ago, between the late 8th and early 9th centuries, during a time when Merv was part of the Abbasid Caliphate and regarded as one of the most enlightened cities in the Islamic world. At that time, Khorasan was governed by Abdullah al-Ma’mun, the son of the famous Caliph Harun al-Rashid. Al-Ma’mun, who was known for his interest in astronomy, became Caliph in 813 but continued to reside in Merv for some time. Historical records suggest that Merv essentially served as the de facto capital of the caliphate during this period, with decrees and appointments for the entire Arab Empire issued from there until al-Ma’mun eventually moved to Baghdad.
