Back in the year 2000, London gained two new attractions, the Millennium Wheel (London Eye) and the Millennium Dome, which has been known as The O2 Arena since 2005! The Millennium Dome started life as a giant museum, I visited when I was 11 and all I remember is a Royal Mint press making £5 coins, a giant body with an escalator that went up it’s leg (?? or arm?) and a relaxation room full of people laying all over the place (me and my dad found it hilarious). It’s now a large music and entertainment venue with shops, restaurants, a cinema, Up At The O2 climb and a few other things.
