"There are no constraints on the human mind, no walls around the human spirit, no barriers to our progress except those we ourselves erect." - Ronald Reagan _ Part 7 of 7 of my Greek Week series. Ancient walls in Thessaloniki - Greece’s 2nd largest city. _ These beautifully ornate fortifications were built by the Byzantines around 390AD and still stand today. _ There are few places in the world where the evidence of colliding empires is so vivid as this particular city. With over 2,300 years of civilization, this region has been home to ancient Greeks, Romans, Byzantines, Ottomans and finally modern Greeks. Each empire left its mark both culturally and materially – in the architecture, in the food, in the way of life. _ Thessaloniki has been the cradle of innovation in ancient times and still flows with the same creative energy today. _ #ancientgreece
