One Day in Cologne Old Town: Essential Guide & Top 10 Things to Do

Cologne is a German city that rose like a phoenix from the smouldering embers of World War II. In retaliation for the Nazis pummelling London, Allied forces smashed 95 per cent of the city to smithereens.

Undeterred, the city set about putting itself back together at the end of the war. Today’s Cologne is a lively city with a rich historical legacy.

By spending just one day in Cologne Old Town (Aldstadt) you will be able to visit its key attractions, including its world-famous cathedral, and try some of the food and beer for which the city is famous. Whether you are here for the first time or are a repeat visitor, here are the best things to do in the historical heart of one of Germany’s most interesting cities.

One Day in Cologne Old Town: Best Things to Do

1. Visit Cologne Cathedral

Cologne Cathedral defies superlatives. This UNESCO-listed Gothic masterpiece is the tallest twin-spired church in the world and one of Europe’s most popular tourist attractions.

It owes its existence to the Three Wise Men.

In the 12th Century, the bones of the Three Kings were brought to Cologne from the conquered city of Milan. This drew pilgrims in their droves and attracted funding to build a cathedral that was magnificent enough to house the Magi’s mortal remains. Their bones are housed in a lavishly gilded reliquary.

The Cathedral is also home to the exquisite 10th Century Gero-Crucifix and the Madonna of Milan, a wooden sculpture said to possess miraculous powers.

Address: Domkloster 4, 50667 Köln

Entrance fee: Admission to the cathedral is free. A small fee applies if you wish to climb the 533 steps up the South Tower or visit the Cathedral Treasury.

Opening hours: Check the cathedral’s official website for opening hours and information about their guided tours in English

2. Peek at the Roman mosaic at the Roman-Germanic Museum

Cologne was founded as a Roman settlement in 38 BC and became a colony – Colonia Claudia Ara Agrippinensium to give it its full name –  in 50 AD. If you peer through the window of the Roman-Germanic Museum (Römisch-Germanisches Museum), you will be able to see evidence of Roman life in Cologne.

A fine mosaic floor that was once in the dining room of a merchant depicts saucy scenes from the life of Dionysus. This would have been at the original Roman street level.

At the time of updating this post (August 2023), the Roman-Germanic Museum remains closed for renovation. An interim exhibition comprising a quarter of the permanent collection has moved to the Belgisches Haus (Cäcilienstraße 46).

3. Walk over Hohenzollern Bridge

Hohenzollern Bridge (Hohenzollernbrücke) may be the busiest railway bridge in the world – more than 1,200 trains daily but who’s counting – but that’s not why it is a tourist magnet. People visit this Cologne landmark for its classic Industrial Age design and for its love locks.

Although love locks are a familiar sight in cities across the globe, I have never seen as many as there are on Hohenzollern Bridge. Couples inscribe their names and date on a padlock, chain this to the bridge railing and chuck the key over the bridge as a symbol of their everlasting devotion.

I recommend walking all the way to the other side of the bridge for a fabulous view of Cologne Cathedral.

4. Get your cocoa fix at the Chocolate Museum

Walk back over Hohenzollernbrücke, pass the statue of Kaiser Wilhelm II, who paid for the bridge, and take the steps down to the pleasant riverfront park. A ten-minute stroll along the river will bring you to Cologne’s famous chocolate museum (Schokoladenmuseum).

Chocoholics shouldn’t miss this place. The three levels of this absorbing museum trace the journey of the cocoa bean to the finished thing. It’s at least the equivalent of the ChocoStory museums in Bruges and Brussels.

This is one of the things to do in Cologne that is worth booking in advance.

5. Explore the squares of Cologne Old Town

Retrace your steps along the river to the diminutive Fischmarkt, one of the squares of Cologne’s historic centre. As its name suggests, this was once the fish market.

Although the buildings look medieval, they are much younger.

In the early 20th Century, the Nazis rebuilt Cologne’s scruffy Old Town in a sanitised stone-and-stucco style that was more to their liking. This was their vision for old towns across Germany.

That didn’t last long. After the Second World War, Cologne was rebuilt in the faux-medieval style that we see today.

A few minutes inland from Fischmarkt is Alter Markt (Old Market Square).

Alter Markt, Cologne

In the middle of the square is a late 19th Century fountain. This was built to commemorate Jan von Werth, a victorious army general who served in the Thirty Years’ War. Its reliefs tell the story of the unrequited love between von Werth and Griet, a woman who rejected him as he wasn’t from a wealthy family.

This historic square is the setting for one of Cologne’s famous Christmas markets.

6. Take a look at Cologne’s Rathaus

Alter Markt is also home to the Old Town’s City Hall.

The Rathaus’s Renaissance porch is the sole historic survivor of the 1945 bombings. It’s also worth circling the building to view the carvings on the side of the building.

7. Visit Cologne’s Romanesque churches

Twelve large Romanesque churches are set in a semi-circle around Cologne’s city centre. Built between 1150 and 1250, these predate Cologne Cathedral.

If you have just one day in Cologne, I suggest focusing on two of these: St. Gereon and Groß St. Martin (Great St. Martin’s Church).

Visit Saint Gereon for its gravity-defying decagonal dome. This minor basilica was architecturally ahead of its time and has been compared with the Hagia Sofia in Constantinople and the Brunelleschi’s dome in Florence.

By contrast, Groß St. Martin has a modern, almost minimalist interior. It was built on the site of Roman warehouses, the columns of which were used in its construction.

For a small fee, you can visit the archaeological excavations in the church’s crypt.

Great St. Martin’s Church is better known for its distinctive exterior with its ensemble of four slender turrets embracing a central spire that towers above Fischmarkt.

8. Buy Cologne from Cologne

It has to be done.

I recommend visiting 4711. Housed in a historic building on Glockengasse – it takes its name from its street number in the Napoleonic era – this iconic Eau de Cologne was produced in the city as early as 1799.

A shop on the ground floor sells a wide variety of fragrances and gifts to buy for those back home (or for yourself), and there’s a small museum on the mezzanine level.

Alternatively, head to the place where it all began: Farina 1709. It was here that Johann Maria Farina launched the original Eau de Cologne in 1709. There’s a shop and museum which you can visit on a guided tour.

9. Take a relaxing cruise along the Rhine

Cologne marks the northern end of the Romantic Rhine Valley and you can view Cologne Old Town from a different perspective by joining a panoramic city cruise. This one-hour cruise includes an audio guide.

But if you are looking for more classic Rhine views, consider taking a longer river cruise to Königswinter through Siebengebirge. For more information and to book, click here.

10. Sample the local brew

Leaving one of the best things to do in Cologne ‘til the last. Kölsch is the city’s local brew, a pale, hoppy and slightly sweet beer.

I liked it.

Visiting one of Cologne’s beer halls (Brauhaus) is an experience in itself. You will continue to be served with Kölsch until you say stop (put your beer mat on top of your glass to indicate this). It pairs extremely well with substantial portions of hearty German food.

This is not a great country for vegetarians.

I can recommend Brauerei zur Malzmühle, a traditional family brewery at Heumarkt.

If you want to understand more about Kölsch and Brauhaus culture and benefit from the insider knowledge of a local guide, why not join a beer tour? Although I didn’t have time to do this when I was in Cologne, I did join a beer tour when I was visiting Ghent which was huge fun.

Where to Stay in Cologne

One of the beauties of Cologne is that you easily visit its main attractions in a day. The city’s landmarks are clustered near the train station within a 15-minute walk of each other.

However, for a more relaxed visit and to experience a lively Brauhaus at night, I recommend spending at least one night in Cologne. For maximum convenience, stay in or close to the Old Town.

Is Cologne Safe for Female Solo Travellers?

There are plenty of things for the solo traveller to do in Cologne, from exploring its cathedral and churches to trying the varieties of beer that the city has to offer. Whilst is a big city, as its main sights are within close proximity to each other it is very walkable.
 
I had heard a few horror stories about Cologne in recent years but as a female solo traveller, much of Cologne Old Town felt safe. That said, the area around the train station felt edgier and is best avoided late at night. The strong police presence here is a bit of a clue.
  
As with any big city, to stay safe as a solo traveller, a little bit of common sense goes a long way. Remain vigilant, stick to busy areas, keep your belongings close to you and use your hotel safe to store valuables.

Is Cologne Worth Visiting?

Don’t visit Cologne expecting a quaint storybook city. There are better places in Germany to tick that box.

But don’t let that put you off. Instead, you will get an awe-inspiring UNESCO-listed cathedral, a clutch of first-rate churches and museums, a sympathetically reconstructed Old Town and a lively bar and restaurant scene.
