Cologne is just a quick hour train ride from Frankfurt, but it feels worlds away with its warm, welcoming atmosphere and beautiful surroundings. The heart of the city is undeniably the Kölner Dom (Cologne Cathedral), which became my favorite part of my stay. This stunning Gothic masterpiece towers over the city, and its intricate architecture never failed to leave me in awe. The city itself is charming and lively, with a rich history and vibrant street life that made wandering around a joy. Cologne’s mix of history, culture, and warmth makes it an absolute must-visit.
