Sachsenhausen

Visiting the Konzentrationslager Sachsenhausen in Oranienburg, just north of Berlin, is a sobering and deeply educational experience. Established in 1936 by the SS, Sachsenhausen was intended as a model camp, both in its design and its function. Initially, it held political prisoners, but over time, its population expanded to include Jews, Roma, Sinti, homosexuals, Jehovah’s Witnesses, and Soviet prisoners of war. The camp became notorious for its harsh conditions, forced labor, medical experiments, and systematic executions. After the end of the Nazi regime, the site was repurposed by the Soviets as a special camp for political prisoners and former Nazis, where thousands more perished.

Eurostar

The Eurostar is a remarkable high-speed train service that connects London with several major cities in mainland Europe, including Paris, Bruxelles, and Amsterdam. Its story began in the late 20th century, following the completion of the Channel Tunnel – a monumental engineering feat that links the United Kingdom and France beneath the English Channel. The first Eurostar trains started running in 1994, revolutionizing cross-channel travel by offering a swift, comfortable alternative to air and ferry routes.

Euston underground

Euston Underground Station in London is a fascinating place for anyone interested in the city’s transport history. Located beneath the mainline Euston railway station, it has served as a key interchange for generations of travellers. The original Euston station opened in 1837 as the capital’s first mainline railway terminus, connecting London with Birmingham. Over time, the underground station evolved to accommodate the growing network, and today it is a major hub for the Northern and Victoria lines, serving millions of passengers each year.

Written treasures

The British Library in London is a true sanctuary for anyone passionate about history, literature, and culture. Its origins trace back to the 18th century, when the collections of Sir Hans Sloane, Robert Harley, and Sir Robert Cotton were brought together to form the core of the British Museum’s library. Over time, these collections expanded with royal donations and acquisitions, eventually leading to the establishment of the British Library as a separate entity in 1973. The library’s current home, a striking modern building near St. Pancras, opened its doors in 1998 and now houses over 170 million items, making it one of the largest libraries in the world.

Mail Rail

Beneath the bustling streets of London lies a unique piece of the city’s industrial heritage: the Mail Rail. Originally known as the Post Office Railway, this driverless, narrow-gauge railway was built in the early 20th century to transport mail quickly and efficiently between major sorting offices across the city. Construction began in 1915, but due to the disruptions of World War I, the railway only opened in 1927. For 76 years, the Mail Rail operated tirelessly, shuttling letters and parcels through six and a half miles of tunnels, until it was finally closed in 2003 as road transport became more practical for the Royal Mail.

Bunker Valentin

Located near Farge on the banks of the river Weser just outside Bremen, Bunker Valentin is one of the largest above-ground bunkers in Europe and a haunting reminder of the final phase of World War II. Construction began in 1943, as the Nazi regime sought to protect its crucial submarine production from relentless Allied bombing. The plan was to assemble the advanced Type XXI submarines here, using innovative assembly-line techniques inside a massive, bomb-proof structure. The parts would have been preproduced in Hamburg and Danzig; the idea was to release a new U-Boot every 56 hours. The bunker stretches an astonishing 426 meters in length and 97 meters in width, with walls and a roof several meters thick – designed to withstand even the heaviest aerial attacks.

Germany’s only high-sea island

Helgoland, Germany’s only high-sea island, has a rich and turbulent history shaped by its strategic location in the North Sea. Originally inhabited since prehistoric times, the island belonged to Denmark for centuries before passing to the United Kingdom in 1807 and finally to Germany in 1890 through the Heligoland-Zanzibar Treaty. Since 1932, Helgoland has been part of the Landkreis Pinneberg in Schleswig-Holstein, a unique administrative arrangement that ensures efficient governance despite its distance from the mainland. Pinneberg was selected as it is close to Hamburg, which has the best connection to the island.

Halunder

The Halunder Jet is the most efficient and enjoyable way to reach Helgoland. This high-speed catamaran is designed for comfort and speed, whisking you from Cuxhaven to Germany’s only true high-sea island in a bit more than an hour. If you prefer a longer ride you can also already start your trip at the harbor of Hamburg, giving you a nice tour on the Elbe river. The Halunder Jet is modern and has panoramic windows as well as spacious decks, and great amenities. The timetable gives you the option to either explore Helgoland in four hours (which is possible with good preparation) and return the same day – or to stay overnight and skip one boat.

Hapag

Stepping into the world of Hapag is like opening a chapter of German maritime history that shaped global shipping for more than a century. Founded in the bustling port city of Hamburg in 1847, the Hamburg-Amerikanische Packetfahrt-Aktien-Gesellschaft – better known as Hapag – quickly became synonymous with reliable transatlantic travel and trade. In its early days, Hapag connected Europe and North America, carrying both hopeful emigrants and valuable cargo across the ocean. Over the decades, it grew into one of the world’s most prestigious shipping lines, pioneering new routes and building some of the largest and most luxurious ocean liners of its time.

Emslandlager

The Emslandlager were a network of 15 camps established by the Nazi regime in the Emsland and Bentheim regions of northwestern Germany. These camps, including the notable Esterwegen camp, were constructed from 1933 and served various functions over time: they started as concentration camps for political prisoners, then became punitive and prisoner-of-war camps, and later housed a mix of convicts, forced laborers, and military prisoners. The camps were notorious for their harsh conditions and forced labor, particularly the draining and cultivation of the surrounding moorlands, which became a symbol of the inmates’ suffering and resilience.
