Wrocław — known for centuries as Breslau under German and Prussian rule — is a major city in southwestern Poland sitting on the Oder River, with a layered history spanning the kingdoms of Poland, Bohemia, the Habsburg Empire, and Prussia. Today it is a vibrant university city, home to roughly 640,000 residents, a UNESCO-recognized Old Town Market Square, and, as Gates notes on camera, approximately 600 whimsical gnome sculptures scattered across its streets. Despite its charming present-day appearance, the city was reduced largely to rubble during the final months of World War II, when Nazi forces refused to surrender to the advancing Soviet Red Army until May 1945. Gates uses Wrocław as his opening location in Season 15's premiere, walking its reconstructed streets to frame the broader story of Hitler's ambition to strike the American mainland — asking, as he puts it on camera, "What if Hitler leveled New York?" The city's turbulent twentieth-century history makes it a powerful backdrop for investigating the Nazi long-range bomber program known as the Amerikabomber.
A settlement at the site of present-day Wrocław is established; the city emerges as part of the early Piast dynasty's Polish kingdom.
Wrocław (then Breslau) passes to the Bohemian Crown under the Habsburgs, beginning centuries of non-Polish rule.
Prussia seizes Silesia and Breslau following the War of the Austrian Succession, initiating a long era of German governance.
Nazi Germany invades Poland on September 1st; Breslau becomes a key hub in Nazi-occupied territory throughout the war.
After a prolonged siege by Soviet forces, the city is left in ruins; postwar agreements transfer it to Poland and it is repopulated largely by Poles expelled from eastern territories.
Gates films the Season 15 premiere of Expedition Unknown (S15E01, "Hitler's Amerikabomber") using Wrocław as his opening location and narrative anchor.
Wrocław's postwar transformation is one of the more remarkable urban stories in modern European history. After the brutal siege of 1945 — in which Nazi commanders declared the city a Festung (fortress) to be held at all costs — much of the medieval and early modern fabric was destroyed. Polish authorities and newly resettled residents undertook a decades-long reconstruction effort, painstakingly rebuilding the Old Town Market Square and many historic facades. The result is a city that looks, at a glance, like it might have survived the war intact, but whose rebuilt streetscapes conceal the scale of mid-century destruction.
The city's broader history is genuinely complex: Wrocław has been, at various times, a Polish, Bohemian, Habsburg, and Prussian city, and it changed hands again definitively after 1945 when the Potsdam Agreement reassigned Silesia to Poland. German-speaking residents were expelled and replaced by Poles displaced from territories absorbed by the Soviet Union — a demographic transformation that gives the city a layered, sometimes contested sense of cultural memory. Historians continue to examine how Polish, German, and Silesian identities intersect in Wrocław's public life.
In the context of the Expedition Unknown episode, Wrocław functions primarily as a historical stage-setter rather than a dig site or archaeological investigation. Gates does not unearth anything in the city itself; rather, he uses its visible war scars — and its visible reconstruction — to pose the episode's central question: how close did Hitler's planners come to bringing that same destruction to the United States via long-range bomber programs? The episode then moves outward from Wrocław to investigate that question more directly.
Dr. Charlie Hall, introduced in the episode as a leading authority on Nazi technology, provides the expert scaffolding for the Amerikabomber investigation that follows Gates' Wrocław opening. The city itself serves as a vivid, on-the-ground reminder of what strategic bombing could accomplish — and what it might have meant if directed at New York or Washington.
Gates notes on camera that Wrocław has produced nine Nobel laureates — a remarkable intellectual legacy for a single city.
The city's roughly 600 bronze gnome sculptures have become an unofficial civic symbol; Gates describes them as scattered "all over the city," including one perched on a smokestack high above the skyline.
Wrocław has passed through the hands of at least five distinct political entities over its history: the Kingdom of Poland, Bohemia, the Habsburg Empire, Prussia, and modern Poland.
The Nazi garrison defending Breslau in 1945 held out until May 6 — two days before Germany's formal unconditional surrender — making it one of the last German strongholds to fall in the European theater.
Wrocław is generally very accessible to visitors, with an international airport, direct rail connections to Warsaw and Berlin, and a walkable city center. The reconstructed Old Town Market Square (Rynek) is the natural starting point, and the city's gnome trail — with reportedly around 600 small bronze figures hidden across the urban landscape — has become a popular tourist activity in its own right. Check current local travel advisories before visiting, as conditions can change.
Wrocław is itself a major city; the nearest large international hub is Berlin, approximately 340 km to the west.
Late spring through early autumn (May–September) tends to offer the most pleasant weather for exploring Wrocław on foot. The city's Christmas market, held in the Market Square, is also highly regarded if a winter visit is possible.
Poland
Poland appears as a broader regional entry in the database, sharing the same wartime historical context that Gates explores throughout the Amerikabomber episode.
Berlin
Berlin is the ultimate destination of the Soviet advance that devastated Breslau in 1945, and Nazi Germany's capital is central to the same WWII power structures Gates investigates.
Normandy Beaches, France
The Normandy Beaches represent the Allied counter-offensive that reshaped the war's outcome — the other side of the same WWII narrative Gates uses Wrocław to frame.
