This image features the original Palais des Nations as it appeared along the lakefront before moving to the new building a short distance away.
There is no description on the back of this card.
With the emergence of the United Nations, this building became insufficient for the expanded requirements, and a new, much larger structure was built a short distance away. This building was repurposed and is now the Hotel Wilson. The Wilson memorial is just barely visible at the waters edge below the trees.
This card likely dates from the 1920s.
