[3] 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.

[4][5] Land reclamation works started in 1982 using rubble from the demolished St Enoch railway station.

[8] 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.

Designed by award-winning architect Sir Norman Foster and often called "the armadillo" by Glaswegians, this new 3,000 capacity building was completed in August 1997.

[16] On 15 November 2015, it played host to Insane Championship Wrestling's biggest show of the year, Fear & Loathing VIII.

[18] In June 2012, Irish pop band Westlife were honoured with four specially commissioned bar stools (to be a permanent fixture at the venue) to mark 49 performances at the SEC Centre where they entertained over 380,000 fans over the years, selling more tickets than any other act.

[22] Work began in July 2021 to prepare it for hosting the rescheduled Climate Change Conference in October and November 2021.
