Three countries, on foot
Aachen is where Germany, Belgium, and the Netherlands meet, and the border is not an abstraction. Walk west out of the city and you are in the Netherlands, walk southwest and you are in Belgium, and the language, the shops, and the food change as you cross. Vaals, the first Dutch town, is 6 km from the center. On the Vaalserberg you can stand in all 3 countries at the same time, at a border post that has been there since 1926.

Charlemagne's capital
Charlemagne made Aachen the main residence of the Frankish Empire, which is why the city is sometimes called the cradle of Europe. Its cathedral, begun in 796, was on the first UNESCO World Heritage list in 1978. The Charlemagne Prize has been awarded here every year since 1950.

The most populous state
Aachen is in North Rhine-Westphalia, which has more than 18 million people and is the most densely populated German state outside the city-states. Cologne is the next stop on the Eurostar line, and the same line carries on to Düsseldorf, Duisburg, Essen, and Dortmund. Brussels and Paris are on it in the other direction.

The hot springs
People settled here 5,000 years ago for the warm mineral springs, and more than 30 of them still rise along the fault lines under the city. The Carolus Thermen are built on them, and the Elisenbrunnen in the middle of town still pours one out for anyone who wants to taste it.
