Cologne sits on the Rhine with two thousand years of history packed into a skyline dominated by one unmistakable silhouette. The cathedral alone took over six centuries to complete. Beyond it, twelve Romanesque churches, world-class museums, distinctive modern architecture along the waterfront, and a fiercely local food and beer culture make this one of Germany's most rewarding cities to explore properly. Give it the time it deserves.
What to see in Cologne
Great St Martin's Church
Cologne's old town is anchored by this late Romanesque church, whose 84-metre tower and four corner turrets rise above the Rhine like a medieval watchtower. Built between the 10th and 12th centuries on Roman foundations, it includes an atmospheric crypt well worth a look. One of the city's most recognisable landmarks.
Basilica of San Gereon
Arguably Cologne's oldest church, this is an architectural oddity in the best possible sense. Its oval floor plan dates to the 4th century, and the medieval decagonal dome above it is said to be unique in the world. Among the twelve Romanesque churches in the city, this one consistently surprises visitors.
Crane Houses
Three buildings shaped like inverted harbour cranes define the Rheinauhafen district's waterfront. Bold, immediately recognisable, and a clear statement about Cologne's willingness to let contemporary architecture make its mark alongside centuries-old churches. They photograph well from across the river, particularly at dusk.
Cologne Triangle
The observation deck on the 28th floor of this 103-metre building on the Deutz riverside delivers sweeping 360-degree views across the city and the Rhine valley. It's one of the finest vantage points in Cologne for taking in the cathedral's scale in relation to the rest of the skyline — and the queues are considerably shorter than at comparable spots.
St Ursula's Church, Cologne
Built on the site where the city's patron saint was martyred, this Romanesque basilica holds one of Cologne's strangest and most striking interiors: a golden chamber decorated with intricate mosaics fashioned from human bones. Coupled with impressive bronze doors, it's a genuinely remarkable visit for those interested in Cologne's religious heritage.
Augustusburg Palace
Just outside the city in Brühl, this UNESCO World Heritage Site is a set piece of 18th-century Rococo. Spectacular frescoes, a grand ceremonial staircase, and manicured gardens make it one of Germany's finest Baroque palaces. An easy half-day trip that rounds out any visit to the wider Cologne area beautifully.
Melaten Cemetery
At 435,000 square metres, this historic burial ground is laid out as a public park — and it functions as one. Elaborate monuments and sculptures spanning centuries of the city's history sit within landscaped grounds that reward a slow, unhurried walk. Among Germany's oldest and most visually significant cemeteries.
Cologne Botanical Garden
Founded in 1864 and ranking among Europe's earliest botanical gardens, it now holds nearly 10,000 plant species across extensive grounds, with greenhouses, fountains, and sculptures throughout. Entry is free, and it draws over a million visitors a year — strong evidence that it delivers. A reliable choice whatever the season.
Audio guide for Cologne with Guipock
A city this layered — Roman foundations under Romanesque churches under contemporary cranes on a Rhine waterfront — genuinely benefits from good context while you're standing in front of it. The Guipock audio guide for Cologne gives you exactly that, built around a GPS-guided map that tracks your position as you walk and alerts you when you reach each point of interest, so you can open the guide at the right moment rather than hunting through menus mid-pavement.
The audio itself is produced using high-quality generated audio across a wide range of languages and regional accents — British English, American English, Australian English, European and Latin American Spanish, French, German, and more. You choose the voice that suits you best before you set off. Everything runs on offline download, too, which means you pull the content over Wi-Fi before you leave your accommodation and the app works without mobile data for the entire visit. No signal anxiety on the Rhine waterfront.
Travelling with family? A single purchase covers your whole group. The family sharing code lets each person access the guide from their own phone, in their own language, without anyone needing to share a screen or a pair of earphones. And if you have younger children in tow, the children's mode delivers the same route with adapted language, shorter stops, and content calibrated to keep them genuinely engaged rather than trailing behind.
The Cologne audio guide app is designed for people who want to understand what they're looking at — not just photograph it. Whether you're spending a focused day in the old town or spreading your visit across the Rheinauhafen district, the Botanical Garden, and a detour to Brühl, the guide structures the experience without dictating it.
