The Atomium, located in Brussels, Belgium, is a giant iron crystal-shaped structure built for the 1958 World's Fair. Visitors can explore its spheres, connected by escalators and stairs, to enjoy panoramic city views, exhibits about its history, and science-related displays. Accessibility is generally good, with elevators available in most spheres, but some areas might pose challenges for those with mobility issues. A solo visit is easily manageable with informative displays, but guided tours offer deeper insights. Peak season is during summer, so expect crowds; winter might have shorter hours. Entry tickets typically cost around €16, and a visit usually lasts 2-3 hours. Consider booking tickets online in advance to avoid queues.
