Shergozikhan Madrassah - The museum of the History of Khorezm Medicine (1718 to 1726)
It is located in the centre of Ichan-Kala in front of the entrance to Pahlavan Mahmud Mausoleum. It was erected by slaves captured in 1718 by Shergozikhan during his raid on Korasan and Meshkhed; together with the loot 5,000 slaves were brought from there. Shergozikhan promised to free the slaves after the construction of the madrasah was finished but did everything possible to delay the completion. Infuriated slaves killed Shergozikhan in the uncompleted madrasah in 1720. His Mausoleum is connected to the western corner of the madrasah's main facade. The starting dates and date of completion of the madrasah construction can be found in the work of historian Munis. Shergozikhan madrasah is among the oldest and largest in Khiva. Its entrance lies two meters below the street level due to the natural drop of relief and the growth of cemetery layers next to the Pahlavan Mahmud Mausoleum. This madrasah is one- and two-storey building (with two stories at the entrance) comprising a four-ayvan yard, suite of vestibule rooms and a lecturing hall at the transverse axis of the entrance group. Representatives of Khiva Khanate were not the only ones who got education at this madrasah; there were students from Turkmenistan, including famous Turkmen poet Makhtumkuli.
