#4 Greece. Too many strays, and a semi circle Greek theatre. Not Roman style
#15 Venice. I recognize the flag and the facade. The floor was fixed after water damage.
#16 Luxembourg. The bridge and the modern building.
#17-18 Spain? In Euro, with the 1 written like German but people which do not look like Germans The words in Catalon? No. More like Spanish. So, it is not Barcelona. Correction, it is the Boqueria Market in Barcelona. The lamps look the same my photos.
Guests wait here to go to the Sound of Music tour.
