イパチェフ館
Voykov knew Nicholas Ipatiev, and had visited the Ipatiev House before it was selected as the final residence of Nicholas II of Russia and his family. It seems to have been on the basis of information supplied by Voykov that Ipatiev was summoned to the office of the Soviet at the end of April 1918 and ordered to vacate what was soon to be called 'The House of Special Purpose'.
