The Red Porch or Red Staircase, decorated with stone lions, leads into the Palace of Facets in the Kremlin, Moscow.
In old Russian the word krasny meant "beautiful", but today it means "red". This is the same word used for "Red Square".
On the morning of his coronation, the Tsar was met at the Red Porch, where he took his place beneath a large canopy held by thirty-two Russian generals, with other officers providing additional support. Accompanied by his consort and the imperial regalia, he proceeded slowly toward the Cathedral of the Dormition, where his crowning and anointing would take place.
