Strasbourg

Strasbourg Cathedral held the title of tallest building in the world for over two centuries after its spire's completion in 1439, and its single-spire silhouette — the planned second tower was never built — remains a genuinely striking presence over the old town, one of the few Gothic cathedrals in Europe still regularly described in those terms of raw architectural ambition.

The city's identity has been shaped as much by conflict as by architecture. Strasbourg and the wider Alsace region switched between French and German sovereignty four separate times since 1871 — annexed by the newly formed German Empire after the Franco-Prussian War, returned to France after World War I, annexed again by Nazi Germany during World War II, and returned to France once more in 1945. That repeated back-and-forth left a lasting cultural imprint: the local Alsatian dialect, cuisine, and even street names blend French and German influence more visibly here than almost anywhere else in Europe.

Petite France, the old tanners' and millers' quarter along Strasbourg's canals, has become the city's most photographed district — half-timbered houses, some genuinely leaning after centuries of settling, reflected in the water below, connected by a network of small bridges and locks still partially functional.

Partly because of that centuries-long Franco-German tension, Strasbourg was chosen as a seat of the European Parliament, a deliberately symbolic gesture toward postwar reconciliation between the two nations — the Parliament also meets in Brussels, an arrangement widely criticized as logistically inefficient but that persists precisely because of what Strasbourg represents.

Each year from late November through December, Strasbourg hosts one of Europe's oldest and largest Christmas markets, tracing back to 1570 — the entire old town commits to the season with lighting and decoration well beyond the market stalls themselves, drawing visitors from across the continent specifically for it.
