Sheffield's La Chambre is getting set to celebrate its 20th anniversary.

Here's a glimpse inside Sheffield's world famous swingers club La Chambre '“Â as the venue prepares to celebrate its 20thÂ birthday.

The former pub in Attercliffe first opened its doors as a sex club in 1998 - and attracts some 250 frolicking couples from across the UK each weekend to indulge in all sorts of fruity fun and games - and we've delved into our archives to reveal a sneak peek inside.

Barry and wife Marie Calvert - who has slept with more than 3,000 men during a lifetime of swinging - were responsible for opening the club - formerly the Robin Hood pub - on Attercliffe Road and the pair have written books about their escapades at La Chambre which has 20,000 members.

The club boasts a sauna, swimming pool as well as a torture dungeon and upstairs "playrooms" where men and women gather each weekend for mutual fun.

A Las Vegas newspaper once voted it the third best visitor attraction in the world. Top was the Grand Canyon.

The club in Attercliffe Road comes alive each weekend.

So take a look behind the closed doors of La Chambre as we say happy 20th birthday!
