The Barcelona Pavilion was built in 1929 and designed by Rohe. This particular architecture is one of the more modern looks, especially for its time. It has great open windows to allow natural light into the building. Additionally, it seems to be constructed using plenty of natural rocks. I really enjoy this building because of how lightly designed it is. The great big windows are a great use for day time lighting. It also has this large body of water right outside the building filled with plenty of smoothed stones.
