Kalta-Minor - the "Short minaret". The minaret and Muhammad Amin-khan Madrassah were intended to finish the plan of the big square near the western gates of Ichan-Qala. Kalta-Minor should have become the biggest and highest minaret in Central Asia. Its massive base is 14.2 m in diameter. However, construction was interrupted upon the death of Muhammad-Amin-khan in 1855 after a battle with the Turkmen as historian Munis reported.
