There are many notable examples of Art Nouveau architecture around the world, from the Jugendstil buildings of Germany to the Secessionist buildings of Austria.

One particularly striking example is the Casa Milà in Barcelona, Spain, also designed by Antoni Gaudí. This building features undulating walls, wrought-iron balconies, and a rooftop terrace that offers stunning views of the city.

Another notable example is the Stoclet Palace in Brussels, Belgium, designed by Josef Hoffmann. This building features a facade adorned with intricate mosaics and a grand staircase that leads to a series of richly decorated rooms.
