Standing for 1,500 yrs., is still one of the most outstanding monuments of the world. It has massive domes, was the world's largest building and an engineering marvel of its time. It was reported an attraction of 3 million visitors annually.
It was originally built for the Greek Orthodox Christian Church in AD 537, and later converted into an Ottoman mosque in 1453. In 1935, it was secularised into a museum, retaining the mural of virgin Mary and displaying Arabic calligraphy side by side. It remained the world's largest cathedral for nearly a thousand years, until Seville Cathedral was completed in 1520.
Massive scaffoldings occupying almost one half of the interior remained in sight when we were there. It was the same 5 yrs ago. Restoration works seems endlessly ongoing. It will do no justice to capture the interiors that include the unsightly scaffolds with large drapes and hoardings all over the places.
In this photo, I have done a complete make-over to camouflage the side of the unsightly restoration work (almost halve of the photo). At a glance without serious scrutiny, I believed one would not notice it.
