1. Introduction: Flensburg – A Modern City with a Rich Maritime and Fishing Heritage

Flensburg is a modern city located at Flensburg Fjord, with a charming harbour, maritime museums, and a variety of cultural attractions. Its vibrant old town features a pedestrian street lined with shops and historic buildings, along with idyllic inner courtyards and former packhouses. Taking a closer look at the older buildings reveals how history naturally blends with modern life and tourism.

Standing at Flensburg’s harbour, we cannot help but imagine the many ships that once sailed to and from the East Indies, carrying rum and spices. Today, remnants from this era remain as rum houses and restored warehouses, standing as witnesses to the golden age – the city’s heyday. As one of Flensburg’s tourist brochures describes: ‘The gold of the Caribbean made Flensburg both wealthy and famous’.

There is no doubt that Flensburg’s maritime roots have shaped the city into what it is today. It might not be obvious at first glance, but if you look a little closer, sightseeing in Flensburg becomes a journey through its fascinating seafaring past.

2. What Was the West Indian Trade in Flensburg

Flensburg’s harbour still echoes its maritime heritage. As we stand outside one of the old rum houses, we imagine the hustle of 18th-century traders unloading spices and spirits from ships, as described at the Maritime Museum.

Flensburg was Danish for over 400 years and was therefore part of the Danish colonial empire, which, among other things, sailed to the Danish West Indies (St. Thomas, St. John, and St. Croix – modern-day U.S. Virgin Islands). In the 18th century, the city became one of the most important ports for trade with the West Indies, from where they brought back cane sugar and rum.

The Wein- und Rumhaus Braasch is one of the few remaining rum houses in Flensburg.

In the following centuries, rum producers in Flensburg further refined the Caribbean rum in the so-called rum houses. The rum houses were central to the local economy, with some even developing secret recipes that became local treasures. Although the number of rum houses has decreased over the past decades – from around 25 just 50 years ago – a handful remain in the city today as cultural landmarks, including the Wein- und Rumhaus Braasch.

Johannsen Rum House, the oldest rum house in Flensburg still in operation.

Strolling along the pedestrian street, we immediately spot ‘Braasch Rum’, tucked between the modern shops. This continues the original rum tradition, with Walter Braasch carrying on an adapted old recipe, having created a ‘classic rum’. In another side street, we come across another of the old rum production houses in Marienburg, ‘Johannsen Rum’, the oldest rum house in Flensburg still in operation.

A renovated packhouse dating back to the West Indian trade era.

The historic packhouses, once used to store goods such as sugar, rum, and spices from the Danish West Indies, have been carefully preserved and stand as enduring symbols of Flensburg’s maritime trading past. Some, like the ‘Vestindenpakhus’, have been thoughtfully renovated and now serve as residential and office spaces.

3. Historic Ships and Harbour

Flensburg Harbour.

As a tribute to Flensburg’s centuries-old rich history as a vital trading and seafaring hub, the harbour today is alive with a fleet of wooden ships reflecting the city’s maritime heritage. Alongside meticulously restored vessels, newly crafted ships set sail for scenic cruises, harbour tours, and vibrant cultural events. These majestic wooden ships stand as living symbols of Flensburg’s captivating nautical past and attract locals and visitors alike.

Walking through the harbour to see the historic ships, we try to imagine the bustling ships that once sailed here, laden with rum and spices. Several museums showcase Flensburg’s maritime legacy, linking its colonial past with the vibrant present-day cityscape and harbour life.

The salon steamer Alexandra, built in 1908.

One of the harbour’s highlights is the salon steamer Alexandra, built in 1908, and the only passenger ship in Germany still fired by coal. Watching the dusty coal being wheeled on board in traditional barrows is like a scene from another era. The nearby Maritime Museum and museum shipyard offer a rare insight into how the historic ships were built.
Another unique structure is the historic hand-operated wooden crane, once used to load and unload goods from ships. This heritage piece dates to 1726, when the harbour’s operations relied entirely on manual labour and simple mechanisms.

4. Fishing Heritage and Tradition

Flensburg is also a city of fishing history and tradition. Fishing for herring, cod, and flatfish in the Flensburg Fjord and the Baltic Sea was once a common occupation. Local families fished from small boats and sold their fresh catch at the harbour and the town’s markets.

The historic fishing quarter of Sankt Jürgen.

On the east side of the fjord lies the historic fishing quarter of Sankt Jürgen, which still feels like a small village community. Strolling along the main lane reveals an authentic setting with small fishermen’s cottages and former smokeries. It is a charming, old maritime working-class district, with a history that reflects the harsh realities of fishing life.

While steeped in fishing history, the area on a sunny day reveals a peaceful, picture-postcard charm, with vibrant houses and tranquil lanes full of atmosphere. Looking out over the city, it becomes clear how centuries of maritime trade and fishing have helped shape Flensburg’s identity.

5. Sightseeing: What to See and Do in Flensburg

Beyond shopping on the pedestrian street, dining in one of the charming restored inner courtyards or the historic Hansen’s Brauerei – or simply sitting at a sidewalk café soaking in the atmosphere of this old Danish trading town, it is rewarding to combine your visit with cultural sightseeing that offers insight into Flensburg’s historic role.

Several maritime museums, such as the Maritime Museum, Rum Museum, and the Museum Harbour & Shipyard, offer a vivid insight into Flensburg’s past as a rum trading city and a key maritime hub between Denmark and the West Indies. There are also historic walking and harbour tours, both on foot and by boat.

To showcase the city’s heritage attractions, several captivating self-guided walking tours lead you past historic ships, atmospheric warehouses, and key landmarks along the waterfront and through the heart of the city. Two popular routes are the Rum and Sugar Route and the Captain’s Route. Complementing these cultural sights, the old town’s charm is beautifully enhanced by the maritime atmosphere and idyllic scenery along the fjord.
