The SSE Hydro is a multi-purpose indoor arena located within the Scottish Event Campus in Glasgow, Scotland. The arena was initially named The Hydro after its main sponsor, energy company Scottish & Southern Energy subsidiary Scottish Hydro. The company then re-branded itself and its subsidiary companies as SSE, however the Hydro name was retained despite it no longer being a trading name. The arena was designed by the London-based architects Foster + Partners and officially opened on 30 September 2013, with a concert by Rod Stewart.
In 2016 the arena handled 751,487 ticket sales; making it the eighth-busiest music arena in the world in terms of ticket sales. It also hosted the UFC’s first event in Scotland – an event which was impossible to hold in any other arena in the country.
