Architecture is more than just the layout and shape of a building. Not only is it an art form that represents different eras in history, but also one that can define an entire city. Just think: We immediately associate Barcelona with the organic designs of Antoni Gaudí, and you can’t possibly picture Miami without immediately conjuring up images of the Art Deco houses on Ocean Drive.
From the iconic churches of Florence to the concrete behemoths of Skopje, we’ve rounded up some of the best cities for architecture lovers. You’ll find both ancient wonders and contemporary marvels, famous skylines and quiet neighborhoods, big cities and unassuming towns—all bound by the common thread of being virtually inseparable from their visual designs and the architects behind them. Here, enjoy 20 of the world’s top architectural movements and the cities that best showcase them.
