A third tower was built in 2011–2014, making the venue one of the five largest in Europe, with a room capacity of over 1,200. The third tower is the tallest building (100 m (330 ft)) in Gothenburg and the fourth tallest in Sweden.
In the early 20th century a variety of Swedish companies arranged fairs in order to promote Swedish industry. Hence emerged the idea of a congress centre, and on 8 July 1918 the official Swedish Exhibition and Congress Centre was opened.
The centre has nine exhibition halls, 60 meeting rooms (from 2 to 8,800 guests), a congress hall for 1,500 people, eight restaurants, five bars and Scandinavia's largest hotel, Gothia Towers. The centre has an area of 41,000 m2 (440,000 sq ft) for exhibitions and congresses, and each year about 30 exhibitions are held with 8,000 exhibitors. Festivities and banquets are held at the venue with up to 8,000 guests.
The location of the Congress Centre was decided by different trade commissions and industry corporations when Svenska Mässan was established. The location is efficient since it is in the middle of Scandinavia, equidistant to the three capitals of Sweden, Denmark and Norway – Stockholm, Copenhagen and Oslo. The central location also places the venue within walking distance of hotels, restaurants, pubs, shopping malls and theatres.
