The Firehall is a building originally constructed in the 3rd century by Volodymir Rurikson? to enclose Rurik's Pyre. It became the center of Medvedgorod, which in turn became the root of what is now the Matriarchate of Periaslavl.
It and has been rebuilt and updated often. Now it is a part of the much larger palace where the velikomat and velikodoch reside called the Dvorets Materi. Most ceremonies involving the velikomat or velikodoch are performed here.
