The old city center of Krakow is without a doubt the easiest place I’ve ever navigated. All of the roads surrounding the main square follow the basic grid pattern making it nearly impossible to get lost and the entire space is bordered by a beautiful green park at once served as the city's moat. In the heart of the city lies the main square lined with dozens of buildings wonderfully painted in vibrant colors. No structure is taller than six stories and the facades remain more or less the same as when they were first constructed. Unlike so many other cities that were either demolished or razed during Nazi occupation in WWII, Krakow was considered a German heritage site and was thankfully spared from any significant damage.
