The "Pavilion of Provisional Happiness," created by brewery Jupiler, is to be part of the city's celebrations marking the 50-year anniversary of Expo 58, also known as the Brussels World's Fair, Flandersnews.com reported Wednesday.

The beer crate pavilion is being built near the Atomium, a famous structure built for Expo 58 that models an iron crystal cell with spheres that represent atoms.

Screenings of the historic film "Expo 58" are scheduled to be shown on the pavilion, which is expected to open to the public April 17.
