Russian Blonde Girl On The Roof Of The House With Saint Basil's Cathedral In Background

“On the Trinity on the Moat in Moscow.
In the same year, through the will of tsar and lord and grand prince Ivan began making the pledged church, as he promised for the capture of Kazan: Trinity and Intercession and seven sanctuaries, also called "on the moat". And the builder was Barma with company.”
Identity of the architect or architects is unknown. Tradition held that the cathedral 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 recreate the masterpiece elsewhere, although the real Postnik Yakovlev remained active at least throughout the 1560s. There is evidence that construction involved stonemasons from Pskov and German lands.
