Istanbul: Sultanahmet - Hagia Sophia

Another step, and the huge dome above it has dwarfed the distant apse. No! It is only a semi-dome, with a circle of windows swimming into view high above.
A few steps more and you stand at the Imperial Door, and finally the last secret is revealed as the enormous gilded dome soars above the vast inner space of the nave, the small windows at its base lifting it with coloured light
