Oswald Mathias Ungers - Germany
Trade Fair Hall 9
Ludwig-Erhard-Anlage 1, Frankfurt
1980 - 1983

Before Oswald Mathias Ungers built his famous gatehouse for the trade fair complex Frankfurt, he had already designed
two buildings on the fairgrounds. These were the Hall 9 and the glass passage, called "Galleria" which connects the Halls 8 and 9.
The monumental effect of the Gallerie, which is about 30 meters high and 120 meters long and which is covered by a barrel vault,
is mitigated through the transparent outer skin. This emphasized transparency symbolizes the openness of the exhibition
as a trading center and place of exchange. In its dimensions, the massive glass hall recalls the Milan Galleria Vittorio Emanuele II.
Together with the "Galleria", the rooftop of Hall 9, which is lined with tree balls, sets a sign at the entrance to the city from the highway
which is visible on long distance. Already in its original state, the Hall 9 had imposing dimensions, and was then further extended in 1996.
Since then, the Hall 9 is the largest hall at the exhibition center with a gross exhibition space of 56`000 square meters.
With the stepped plinth area of the building, the height of the adjacent Hall 8 is adapted, so that it conveys skillfully between the height differences.
The also adjacent Hall 10 was increased in 1992 by Oswald Mathias Ungers and redesigned with a new facade.
