The identity of the architect is unknown. Tradition held that the church was built by two architects, Barma and Postnik: the official Russian cultural heritage register lists "Barma and Postnik Yakovlev". Researchers proposed that both names refer to the same person, Postnik Yakovlev or, alternatively, Ivan Yakovlevich Barma (Varfolomey). Legend held that Ivan blinded the architect so that he could not re-create the masterpiece elsewhere. Many historians are convinced that it is a myth, as the architect later participated in the construction of the Cathedral of the Annunciation in Moscow as well as in building the walls and towers of the Kazan Kremlin. Postnik Yakovlev remained active at least throughout the 1560s.
