Barcelona earns fourth for Gaudí’s Sagrada Família and Park Güell, the Gothic Quarter and the option of time by the sea. It changes the mood of a short stay beyond another museum itinerary.
That mix puts it above Istanbul for our general first-trip brief, while London offers a broader cultural menu. Choose one Gaudí landmark as an anchor, then explore old streets on another part of the trip. Do not rank it first solely for a beach: this list prioritises historic sights before leisure variety.
