Walking on the Hohenzollern Bridge, there are lovers locks everywhere, secretly thinking that the future of the bridge is worrying, I don't know if it will be like the Art Bridge in Paris, and it will be overwhelmed. The famous Cologne Cathedral is on the side of the Hohenzollern double-curved bridge, but unfortunately the church is under repair. The spire of the church stands on the square. The Cologne Cathedral is the second tallest church in Germany. His construction took more than 600 years and is a representative work of medieval European Gothic architectural art. When you arrive in Cologne, you must come to this century-old shop, the Rhine Pork Elbow Shop. To be honest, it is color, fragrance and taste. The skin of the pig elbow is very crisp, the meat is delicious, and the outside is hot and tender. And the weight is very large, two people will feel very full if they only eat one pig elbow.
