Progress on the restoration of the Parthenon, the Temple of Athena
Nikei and the Propylaia: Part A, what the Parthenon, Temple of
Athena Nikei and the Propylaia looked like BEFORE restoration:

The restoration of  Parthenon, the Temple of Athena Nikei and the
Propylaia is making fantastic progress as of 2018. To put it all in
context, I am posting here the deplorable condition of these 3
landmarks in the 15th., 17th. and 19th., centuries, before restoration.
Here you see two views of of the Ottoman Acropolis in 1456. It is still
in magnificent condition. Notice that the Ottomans did not desecrate
the beautiful frieze of the parthenon, much to their credit as an
advanced civilization.

What a terrible shame while it was being used as a gunpowder
magazine, that it was hit by artillery shot and damaged severely and
blown to bits by the Venetians in 1687 as seen here. The buildings of
the Acropolis suffered significant damage during the 1687 siege by the
Venetians in the Morean War, fought between the Republic of Venice
and the Ottoman Empire between 1684 and 1699. Here you see a
black and white rendition of that terrible destruction:
