These are really excellent graffiti ... Historical landmark really fascinating and I am sure anyone can learn and know about portu by watching this graffiti... I love how every landmark picture separated from each other by the trees ... Looks like frame or pillars .. Is that graveyard behind the wall?? Wow , I would never know if I don't read the post... 6 pieces of art turned out beautifully in one frame of panoramic view... Nice post buddy...
