Orthodox churches generally take one of several shapes that have a
particular mystical significance. The most common shape is an oblong or
rectangular shape, imitating the form of a ship. As a ship, under the guidance
of a master helmsman conveys men through the stormy seas to a calm harbor, so
the Church, guided by Christ, carries men unharmed across the stormy seas of
sin and strife to the peaceful haven of the Kingdom of Heaven. Churches are
also frequently built in the form of a Cross to proclaim that we are saved
through faith in the Crucified Christ, for Whom Christians are prepared to
suffer all things. Less frequently churches are built in the shape of a circle,
signifying that the Church of Christ shall exist for all eternity (the circle
being one of the symbols of eternity) or in the shape of an octagon, signifying
a star, for the Church, like a star, guides a man through the darkness of sin
which encompasses him. Because of the difficulties of internal arrangement,
however, the latter two shapes are not often used.
Almost always Orthodox churches are oriented East West, with the main
entrance of the building at the West end. This symbolizes the entrance of the
worshipper from the darkness of sin (the West) into the light of Truth (the
East). This rule is violated only if the building had been previously
constructed for another purpose, or if services are conducted in a private
home, for example, when the entrance and main portion have been arranged
according to convenience. On the roof of Orthodox churches are usually found
one or more cupolas (towers with rounded or pointed roofs), called crests or
summits. One cupola signifies Christ, the sole head of the Christian community;
three cupolas symbolize the Most- Holy Trinity; five cupolas represent Christ
and the four Evangelists; seven cupolas symbolize the Seven Ecumenical Councils
which formulated the basic dogmas of the Orthodox Church, as well as the
general use in the Church of the sacred number seven; nine cupolas represent
the traditional nine ranks of Angels; and thirteen cupolas signify Christ and
the Twelve Apostles.
A peculiar feature of Russian Orthodox churches is the presence of
onion-shaped domes on top of the cupolas. In the early history of the Russian
Church, especially in Kiev, the first capital, the domes of the churches
followed the typical Byzantine rounded style, but later, especially after the
Mongol Period, Russian churches tended toward the onion domes, which, in many
places, became quite stylized. Historians are not in agreement as to the origin
of this particular style, but some point to the possible influence of Persia on
this peculiar feature of Russian church architecture, while others argue that
since this style was more popular in the far North of Russia, it had a
practical application, in that the shape was particularly suited to shed the
large amounts of snow common in the region.

OF THE DOMES OF ORTHODOX CHURCHES

HISTORY

COLORS
NUMBER
The number of domes on Orthodox churches carries theological significance.
Some architects favor a three-dome arrangement to represent the persons of the
Trinity: Father, Son and Holy Spirit. Others choose a five-dome configuration
to represent Jesus and the four Gospel writers: Matthew, Mark, Luke and John.
SYMBOLISM
The symbolism of the colors of Orthodox domes is not strictly assigned, but
can be extrapolated from the rules guiding Orthodox art. For instance, in
Orthodox iconography, gold represents the light of God and his divine nature.
Red is traditionally a reminder of the passion and suffering of Jesus and the
martyrs, but also signifies the Resurrection and eternal life. Green is the
color of the Holy Spirit, the natural world and new life. Blue is a color
associated with the “God bearer,” or mother of Jesus, Mary. White is another
symbol of the light of God, and is also used to denote righteousness, purity
and holiness.
