The Fira de Barcelona, one of Europe’s biggest trade fair institutions, boasts two locations. Since 1932, the conference and trade centre has hosted a slew of shows and congresses with the economy’s main areas, such as technology and innovation, as subjects. It provides a place for companies and professionals to share (with a hint of competitiveness) experiences and technological development.

One of the biggest conventions held at Fira de Barcelona and Fira Barcelona Gran Via is the Mobile World Congress, the world's largest gathering for the mobile industry, held in February or March every year. The convention focuses on digital empowerment, transformation and innovation.

Sónar, the international music and art festival, also takes place at the Fira locations, which also hosts important bridal conventions or food and drink expos.

The Firas help contribute greatly to the city, and the events they host bring thousands of businesspeople and visitors to Barcelona.
