This must have been a courthouse. The Khan and the three judges entered through the doors aligned with compass points. The cha.m.er owes its dark colour to the dark limestone used in construction, as well as to the smokehouse installed here later.
This building has a legend of its own. During the siege of Bolgar, Aqsaq-Timur (who is known in Europe by the name of Tamerlan) saw the daughter of Khan Abdullah, standing atop the burning building. He fell in love and demanded her hand in marriage. In return, he promised to free her two brothers. The woman agreed, but once her brothers were freed, she threw herself in the flames.
