The Saviour Gate built in the 1670s, at the same time as the walls of the Tsar’s Courtyard, served as an entrance to the household part of the estate. The gate was named after the Christ the Saviour icon, one of those located over the driveway arches. Another name known since olden times is the Back Gate. The gate has a broad driveway and a smaller passage; the gate doors used to be solid. The Streltsy Guard-houses adjoined the gate on the south. It was built in the 1680s and served to provide security inside and outside the Tsar’s residence.
