The National Reserve "Sophia of Kyiv" (Ukrainian: Національний заповідник «Софія Київська») is a historic preserve that contains a complex of museums in Kyiv and Sudak and responsible for maintenance and preservation of some of its most precious historic sites.
In 1934, by the order of the authorities of the Soviet Ukraine, the creation of the cultural reserve at the site of the Saint Sophia Cathedral likely saved one of the holiest sites in Eastern Europe from destruction during the Soviet-wide anti-religious campaign of the early 1930s.
The preserve was established in place of the cathedral of the Ukrainian Autocephalous Orthodox Church that was dissolved in 1930.
The museum's responsibilities were gradually expanded to other historic locations of Kyiv.
In 1994, the reserve was accorded its current status as being National.
