Built in 1417, this is Central Asia’s oldest medressa, and may well be familiar to you as it became a model for many others. The blue-tiled medressa, one of three built by Ulugbek (the others are at Gijduvan, 45km away on the road to Samarkand, and in Samarkand’s Registan complex), is unrestored and much in need of conservation work – the central alcove in the courtyard recently collapsed and work is needed almost everywhere. There are no stalls here, just some empty cells and a small museum with some great old photos, including one of the Kalon Minaret looking the worse for wear after the Soviets bombed it in the 1920s.
