The Hohenzollern Bridge crosses the Rhine at kilometer 688.5. Initially, this bridge was used for railways and highways, but after it was demolished in 1945, this bridge was only used for trains and sidewalks. Named the Hohenzollernbrucke, this bridge is very unique because you can find thousands of love locks bearing the names of couples who have visited this place.

It is not known how many padlocks are attached around this bridge. The reason is, thousands of tourists and residents around Cologne put "love locks" there as a symbol of their affection for their partner.

However, it is estimated that there are around 40 thousand love locks hanging on the bridge to date. This is a fantastic number, considering that the tradition of installing love locks on the bridge only started in 2008. If you calculate it, it means that there are around 40 thousand couples or 80 thousand people who have followed the tradition of installing this love lock.

Even though it is unique, in fact expressing love for your partner by installing a padlock creates new problems on the Hohenzollern Bridge. This is because the tradition of installing love locks makes the bridge weigh around 2 tons. Not to mention, the keys to the locks were thrown into the bottom of the Rhine River, which polluted the river.

Despite all the existing problems, this bridge is actually able to attract thousands of tourists every year. Especially when Valentine's Day arrives, because there are several couples who want to install padlocks

 on the Hohenzollern Bridge, or just walk around and take photos on the walls of this unique bridge.

Past the Museum Ludwig and across Heinrich-Böll-Platz is the footpath onto the bridge. This means that the bridge can be reached in just a few minutes from the main railway station. The Hohenzollern Bridge can also be easily reached from Cologne Deutz Messe station. The distance is 450 m.
