The Cologne Cathedral is a jaw-dropping masterpiece of Gothic architecture. The moment you step out of the central train station, its colossal twin spires tower over you-the sheer scale of it is completely overwhelming and beautiful.Inside, the experience is just as incredible. The massive vaulted ceilings, the stunning, intricate stained-glass windows, and the historic Shrine of the Three Kings are unforgettable. For an extra adventure, you can climb the hundreds of steps up the South Tower for a spectacular panoramic view of Cologne and the Rhine River. It is an absolute must-visit landmark that easily deserves a perfect rating!
