An intriguing mix of old and new, Cologne reveals its Roman heritage in the city layout and ancient ruins that lie scattered through the town. Cologne’s modern plazas and Hohe-Strasse, a pedestrian-only shopping zone, provide a variety of stores, lively bars and enticing restaurants. Of particular note is the city’s 14th-century Cathedral, a stunning example of Gothic artistry that is a UNESCO World Heritage Site. Spared Allied bombs during World War II, the Cathedral’s lacy spires are visible for miles, and its stained-glass windows fill the interior with brilliant colored light.
