The Cathedral of the Dormition was the mother church of Muscovite Russia. The church stands on the Cathedral Square at the Moscow Kremlin and was built in 1475–1479 by the Italian architect Aristotele Fioravanti. Ivan III then invited Aristotele Fioravanti, a celebrated architect and engineer from Bologna, Italy, to come to Moscow and entrusted him with the task of building the cathedral from scratch in the traditions of Russian architecture. The interiour was painted with frescoes and adorned with many holy images.
