Lucca, a Tuscan city surrounded by remarkably intact Renaissance walls, offers more than just postcard views. Known for its quiet streets and grand piazzas, Lucca stands apart with its circular street layout, still following the lines of a Roman amphitheater from centuries ago.

Bamberg, located in northern Bavaria, stands out for its remarkably preserved medieval layout, which earned it a spot on the UNESCO World Heritage list.
