48 metres wide, 15 metres deep, and 18 metres high, and all of that for one person: Robbie Williams.

Well, not exactly one person, as the stage has and will also be used by other big artists, such as the Arctic Monkeys and Paul Kalkbrenner.

It took no fewer than 70 lorries, 50 people, and four days of shipping and assembly to put up the stage.

The approach is very precise: The stage floor is put in place first before the greater structure and roof are installed. This is followed by the eight 15-metre-high towers carrying the stage, positioned using a crane. Once this base has been installed and the tarpaulins fitted to the roof, the latter can finally be hoisted to the top of the towers.

It was only the day before the first concert that the speakers, screens, and lighting were installed. Watch at these fearless technicians rise to the top!

14,000 kilos of volt-amperes are needed to light up the stage and amplify the music so that every last of the 16,000 spectators, the maximum capacity of the 12,000 square metre site, can fully enjoy the concert.

Up to 800 people are working all around the stage to prepare the site for the arrival of these tens of thousands of people who will need to be fed and hydrated, not to mention all the provisions for the teams, backstage personnel, and the wider organisation.

A little tidbit at the end: so-called 'runners' are hired on the day of the events to cater for the stars' every whim and, if need be, move heaven and earth to satisfy any last-minute requests. Did Robbie ask for green M&M's only? We will never know.

Throughout the week, between 10,000 and 15,000 visitors are expected to attend each concert. The tram, which stops right next door, can carry up to 400 people per journey, so the frequency has been adapted and increased every concert night. So, do make sure you use public transport to avoid traffic jams around Luxexpo.
