Hadrian's Library

It's a building that has been destroyed, rebuilt, repaired or repurposed a number of times since it was built in 132/133AD by Roman Emperor Hadrian. Then, it was built as a library; but over the course of 1900 years, it has served the purpose of numerous churches, a cathedral, a mosque, fortification, administration centre, barracks, bazaar and more. Destroyed by pillagers of Athens and by earthquakes and fire, what remains is a testament to its size, massive walls and off course archeological restoration.

The size of its walls and remaining columns is impressive, but the highlight is definitely the mostly intact statue of Nike (Godess of Victory) carved from a single block of marble.
