The purpose of the building was for the display at the Expo, and so the design was purposefully simplified. The real breakthrough came through its use of space, the use of building materials and minimalist design. With that, the Barcelona Pavilion was built using expensive materials, like marble and Trenton stone,
The German pavilion stands on a wide and flat podium. It has a roof that is supported by 8 thin metal columns. Near the pavilion is a pool, and inside the architect actualized the idea of flowing space, with walls that do not connect to one another, or glass walls.
Especially for this pavilion, the architect designed one of the most known chairs in the world of design, a chair that was given the name, "Barcelona Chair." These chairs were used by the Royal Spanish couple, and today this chair is still very successful and considered an icon worldwide. Today it is also sold by the thousands each year.
With the end of the Expo, the pavilion was taken apart, and its pieces were sent on a train to Germany. However, during transportation, many of the pieces were lost. For its great importance, the pavilion was reconstructed, using the exact same materials. For this purpose, the reconstructors collected and analyzed hundreds of photos of the old pavilion, and it was completely reconstructed, apart from the Classical columns that stood at the entrance. From 1986 visitors could come and see the reconstructed pavilion, that was opened for the general public.
Ludwig Mies was educated and especially broad-minded. So he took inspiration, for the planning of the chair, from folding chairs from the ancient Roman period. The result is known: the chair became a real icon, and it is among the most celebrated and loved Modernist furnitures, until today.
