Byzantine walls

It was those damn Christians, Latins from Rome (the Greeks called themselves “Roman”) who sacked the city in the crusades. But the walls were finally breached by the Turks in 1453. It was interesting for me to see a big poster celebrating the 550th anniversary of May 29th, the Fall of the City. Of course, the poster didn't use the word “Fall.” I wonder if Turks like to open up their businesses on Tuesdays?
