Khoren I was murdered in April 1938 by the NKVD. In August of that year, the Armenian Communist Party decided to close down the cathedral, but the central Soviet government seemingly did not approve of such a measure. Isolated from the outside world, the cathedral barely continued to function and its administrators were reduced to some twenty people. It was reportedly the only church in Soviet Armenia not to have been seized by the Communist government. The dissident anti-Soviet Armenian diocese in the US wrote that "the great cathedral became a hollow monument." Revival Etchmiadzin slowly recovered its religious importance during World War II. The Holy See's official magazine resumed publication in 1944, while the seminary was reopened in September 1945. In 1945 Catholicos Gevorg VI was elected after the seven-year vacancy of the position. The number of baptisms conducted at Etchmiadzin rose greatly: from 200 in 1949 to around 1,700 in 1951. Nevertheless, the cathedral's role was downplayed by the Communist official circles. "For them the ecclesiastical Echmiadzin belongs irrevocably to the past, and even if the monastery and the cathedral are occasionally the scene of impressive ceremonies including the election of a new catholicos, this has little importance from the communist point of view," wrote Walter Kolarz in 1961. Etchmiadzin revived under Catholicos Vazgen I since the Khrushchev Thaw in the mid-1950s, following Stalin's death. Archaeological excavations were held in 1955–56 and in 1959; the cathedral underwent a major renovation during this period. Wealthy diaspora benefactors, such as Calouste Gulbenkian and Alex Manoogian, financially assisted the renovation of the cathedral. Gulbenkian alone provided $400,000. Independent Armenia In 2000 Etchmiadzin underwent a renovation prior to the celebrations of the 1700th anniversary of the Christianization of Armenia in 2001. In 2003 the 1700th anniversary of the consecration of the cathedral was celebrated by the Armenian Church. Catholicos Karekin II declared 2003 the Year of Holy Etchmiadzin. In September of that year an academic conference on the cathedral was held at the Pontifical Residence. The latest renovation of the cathedral began in 2012, with a focus on strengthening and restoring the dome and the roof. Architecture Etchmiadzin has a cruciform plan, four free-standing piers, and four projecting apses, which are semicircular on the interior and polygonal on the exterior. Its roof is mostly flat, except the conspicuous central cupola with the typically Armenian conical roof on a polygonal drum and the
