Hagia Sophia, The Cathedral of Holy Wisdom in Istanbul.
Hagia
Sophia (from the Greek: Ἁγία
Σοφία, "Holy
Wisdom"; Latin:
Sancta Sophia).
This
nearly 1500 year old church was
built from 532 - 537.
It
was begun under Emperor Justinian and was intended to be the grandest,
finest church in the world.
For
1000 years it was the
largest church in the world.
Hagia Sophia Cathedral remains
an architectural wonder.
The main dome is supported by an
extraordinary system of interlocking main piers, secondary piers,
buttress piers and spanning arches.
It fell in twice while being
constructed.
When we
were there in 2002 and this year (2014), interior restoration was being
undertaken using scaffolding
as high as a 30 storey building.
Our guide
this year said that they are trying to find ways of strengthening the
supports of the main dome.
The palace of the Sultans from 1462. It was completed in 1478.
There are 4 courtyards in the palace complex.
