Kölner Dom: Cologne Cathedral, with its Gothic architecture, is on the UNESCO World Heritage list. Cologne Cathedral is free to visit. Climbing the tower costs 6 euros. 3 euros if you are a student. For more information, link.

Although it is difficult and tiring to climb the tower, you will think that the view is worth it. Especially those who love to take photos should not miss it.

You can also visit the cathedral treasury. For information, link.

Altstadt (Oldtown): Altstadt is a historic center lined with old restored colorful houses, bars and restaurants. Of course, it is not possible to miss the Old Town area, where you can find the main attractions of the city and then walk by the Rhine, where you can find both peace and activity.

Brunnen der Fichweiber : This square, where you can see the symbolic green, orange, white, yellow and pink building of Cologne, is located in the Altstadt district. You should definitely take a photo at night. Just behind it, you will see the Great St. Martin Church. In the past, the fish transported by the Rhine were sold in the fish market established here. You don't need to search here specifically. While walking around Altstad, your feet will definitely bring you here.

Great St. Martin Church: The church is located in the Old Town square and just behind the Fischmarkt. Although not as magnificent and imposing as Cologne Dom, this is a very nice church. Its history is also very old. Although it has a history dating back to 960 AD, it was badly damaged and renovated in the 2nd World War. Ancient Roman ruins still exist.

Hohenzollern Bridge: This bridge, which was built to replace the damaged bridge in World War II, is used both as a pedestrian and a train track. Before climbing the bridge, you can see the equestrian statue of the German Emperor.

You should definitely do the cliché of putting a lock on the bridge and making your love eternal. Then throw your key into the river so that your love will be immortal.

Hohe street: You can find both brand products and local souvenirs on this street where you can find the stores of H&m, Kiko, Mac and many other big brands.

Roman's Northern Gate: This historical place right in front of Cologne Dom is small but eye-catching.

Roman Germanisches Museum (Römisch-Germanisches Museum): Located right next to Cologne Dom, the museum is a Prehistory and Early History museum.

 You will see many artifacts from the Roman and Germanic periods in the museum, which was built on the site of a Dionysos mosaic. Unfortunately, this valuable museum also suffered losses during the war. We also liked the gift shop section.

Schnütgen Museum: You will find many artifacts from the Middle Ages and especially the Christian world in the museum, where the history of the building dates back to 1130. It has a very large collection with sculptures and crosses. For more information, link.
