Architectural specialists are to this day unable to agree about the governing idea behind the structure. Either the creators were paying homage to the churches of Jerusalem, or, by building eight churches around a central ninth, they were representing the medieval symbol of the eight-pointed star. The original concept of the Cathedral of the Intercession has been hidden from us beneath layers of stylistic additions and new churches added to the main building. In fact, when built, the Cathedral was all white to match the white-stone Kremlin, and the onion domes were gold rather than multi-colored and patterned as they are today.
