The Atomium, in Brussels, Belgium, was designed by engineer André Waterkeyn and architects André and Jean Polak. Built for the 1958 Brussels World's Fair (Expo 58), the Atomium represented scientific progress, technological innovation, and the peaceful use of nuclear energy.

The Atomium featured nine interconnected spheres, each measuring 18 meters in diameter. The spheres were supposed to represent an iron crystal magnified 165 billion times. During Expo 58, the Atomium was a central attraction, offering visitors an immersive and educational experience. Its interior offered exhibitions on science, industry, and culture while its observation decks provided panoramic views of Brussels and the surrounding landscape.

Although the Atomium was originally intended as a temporary exhibit, the building still stands and continues to be a major tourist destination, attracting over half a million visitors annually. Visitors can see the exhibitions, including displays on the history of the Atomium and temporary art installations. The Atomium's observation decks are also popular, offering breathtaking views of Brussels.

The Space Needle was designed by architect John Graham and built for the 1962 Seattle World's Fair, also known as the Century 21 Exposition. This futuristic tower was designed to represent innovation and progress, reflecting the Space Age optimism at the time.

At 605 feet, the Space Needle quickly became the centerpiece of the Seattle World's Fair, offering visitors breathtaking views of the city and the surrounding Puget Sound region from its observation deck. Its unique saucer-shaped design was inspired by the idea of a flying saucer.

After the fair, the Space Needle continued to attract visitors from around the world. Today, the building welcomes over a million visitors annually. You can ride its elevators to the observation deck to enjoy panoramic vistas of the city, dine in the revolving restaurant, and experience the glass-floored observation deck.
