Paris needs no introduction, but here’s one anyway.
Paris is the capital of France and—in terms of metro area—the largest city in the European Union by a HUGE margin. According to the OECD, the population is 11.2 million. For context, the next largest metro area population in the EU is Madrid, at 6.9 million. London (now ex-EU) and Istanbul (definitely not EU) clock-in at 13.4m and 14.6m respectively, according to the same OECD data set. So Paris is more than just a historic, beautiful place (although it is those things as well)—it actually fits the definition for a “mega-city”, in the same league as Mumbai, Mexico City or Los Angeles.
So have you ever considered coming to Geneva? I’m betting the answer is no. Geneva isn’t a common stop-over in European travel, because it has a reputation for being super expensive and (tbh) kind of boring. It’s mostly a hub for international organizations like the WHO, WTO, Doctors Without Borders, and quite a few different UN offices. It’s also got a reputation for being home to a lot of “old money.” So this is a city that really does matter in the world… but might not be quite as relevant for your average traveler.
However, that doesn’t mean the city isn’t still gorgeous! Geneva is surrounded the Alps on all sides, and sits on the southernmost shores of Lake Geneva. It’s just a hop, skip, and a jump from some of the most beautiful terrain in the world, and the city itself is also very pretty.
