If the European coast was built around the sea, this part was built around two entirely different things: hot water rising out of the ground, and mountains.
Europe’s spa towns — Baden-Baden, Évian, Baden in Switzerland — are perhaps the cleanest illustration of this series’ rule. They have existed for centuries because of the springs, and the casino joined them much later, as part of nineteenth-century leisure culture.
Beside them sit three large cities — London, Prague and Bucharest — which are here for the opposite reason: they are so full without it that it barely registers.
