Saint Basil's Cathedral - Structure

Structure

The foundations, as was traditional in medieval Moscow, were built of white stone, while the churches themselves were built of red brick (28×14×8 centimeters), then a relatively new material (the first attested brick building in Moscow, the new Kremlin Wall, was started in 1485). Surveys of the structure show that the basement level is perfectly aligned, indicating use of professional drawing and measurement, but each subsequent level becomes less and less regular. Restorers who replaced parts of the brickwork in 1954–55 discovered that the massive brick walls conceal an internal wooden frame running the entire height of the church. This frame, made of elaborately tied thin studs, was erected as a life-size spatial model of the future cathedral and was then gradually enclosed in solid masonry.

The builders, fascinated by the flexibility of the new technology, used brick as a decorative medium both inside and outside, leaving as much brickwork open as possible; when location required the use of stone walls, it was decorated with a brickwork pattern painted over stucco. A major novelty introduced by the church was the use of strictly "architectural" means of exterior decoration. Sculpture and sacred symbols employed by earlier Russian architecture are completely missing; floral ornaments are a later addition. Instead, the church boasts a diversity of three-dimensional architectural elements executed in brick.
