Octagon on cube

Octagon on cube (also octagon on the quadrangle) is a type of architectural composition in which a building is designed so as the upper octagon-shaped part is placed on the lower cube-shaped part.^[1] This composition has been mainly used to design Russian Orthodox churches.^[2][3]

Initially, this architectural solution became widespread in Russian wooden church architecture. At the end of the 17th century, the style firmly established itself among architects of the Moscow Baroque.^[4] The combination of contrasting forms of this type of church gives striving upward look as dynamism is a characteristic of the Baroque style. Octagon-on-cube churches continued to be built in Russian provinces until the end of the 18th century.^{[citation needed]}

With regard to the Moscow Baroque, there are several different types of octagon-on-cube churches. The main one is a stand-alone, multi-level church, built mainly by the Russian nobility for their suburban estates. The essential attribute of these buildings is a combination of church and bell tower in a single composition. Directly over the octagon level was arranged an open level with eight bells. This type of churches are the starting point for all other versions of the composition.^[5]
