The entire complex of the Centennial Hall areas is highly geometric. For example, a half-ellipse. Hans Poelzig, the creator of the neighbouring Four Domes Pavilion, bent in this characteristic arch the Pergola surrounding the artificial pond (also half-elliptic) on the north-eastern side of the Hall. Two rows of poles made of rough, raw concrete are crowned with a grating, on which a vine will gracefully lay down, giving salutary shade in summer. We counted – there are 750 poles and the length of the whole structure is as much as 640 meters.

Pergola is a place created for taking walks and spending slow, lazy hours on a favourite book reading or casual gossips with friends.
