The Feria de Zaragoza began activity in the year 1941. Afterwards it continued to advance keeping with the trends and evolution of the divisions integrated in the first hall, and started developing a series of monograph halls in a way that the distinct industries needed them: machinery for the construction and public works, agricultural machinery, management of water and environment, equipping of wine cellars and vine cultivation, livestock, new technologies or the energy form just a part of the contents of some of its most specialised fairs. Thus, the Feria de Zaragoza has concentrated on the implementation of high level technical rooms, what has led it to take a lead position at European exhibitions.
