The western part of the city wall of Bukhara, 16th century.

In the mid-9th century, during the viceroyalty of the Tahirids (820-873), an outer wall was built around Bukhara. The city walls were strengthened under the Karakhanids and Khorezmshah Muhammad, destroyed in 1220 by the troops of Genghis Khan, later restored and strengthened by the Timurids Ulugbek and Ibrahim Sultan. Under Abdulaziz Khan, new walls were built in 1540-1549. At the end of the 16th and beginning of the 20th centuries, the city wall of Bukhara, with a total length of 12 kilometers, had 116 rounded half-towers and 11 pairs of towers flanking the fortress gates. The wall was built of pakhsa blocks with adobe bricks in between. The photo was taken in 1959.
