The SEC Centre (originally known as the Scottish Exhibition and Conference Centre until 2017) is Scotland's largest exhibition centre, located in Glasgow, Scotland. It is one of the three main venues within the Scottish Event Campus. Since the opening of the original buildings in 1985, the complex has undergone two major expansions; the first being the SEC Armadillo in 1997, and then the OVO Hydro in 2013. The venue's holding company SEC Limited, is 91% owned by Glasgow City Council and 9% owned by private investors. It is probably best known for hosting concerts, particularly in Hall 4 and Hall 3. Development history The Scottish Development Agency first supported the construction of an exhibition centre in Glasgow in 1979. A site at the former Queen's Dock on the north bank of the Clyde at Finnieston, which had closed to navigation in 1969, was selected. Land reclamation works started in 1982 using rubble from the demolished St Enoch railway station. The construction of the SEC Centre buildings began on the site in 1983. Main Building The Main Building was completed and opened in 1985, with a concert by the Royal Scottish National Orchestra in Hall 1. It later held the Grand International Show in Hall 4 as part of the 1988 Glasgow Garden Festival. In 1990, the SEC Centre was one of the hubs of Glasgow's year as European City of Culture. Upon its opening, the Centre quickly gained its nickname from the local press and thus to general usage, "The Big Red Shed", owing to its outward appearance, which resembled a giant red painted warehouse. The nickname became redundant after the Main Building was expanded and painted grey in 1997. The SEC Centre occupies 64 acres (260,000 m2) of land – most of which is surface car parking space – and hosts numerous music concerts, exhibitions and professional conferences. The SEC Centre also has its own railway station, Exhibition Centre, on the Argyle Line of Glasgow's suburban railway network. The 16 storey Forum Hotel (now part of the Crowne Plaza chain) was opened on the site in 1989. In September 1996, a new exhibition hall, Hall 3, was opened. SEC Armadillo In September 1995, construction began on a new building – the Clyde Auditorium – to become part of the SECC complex. Designed by award-winning architect Sir Norman Foster and often called "the armadillo" by Glaswegians, this new 3,000 capacity
