#2. Principality Stadium (Wales)
The Old Cardiff Arms Park was great but everything about the Millennium Stadium – renamed later as the Principality Stadium – is nigh on perfect save from some early teething problems with the turf which can struggle a little when the roof is on for prolonged periods.
Marler said: ““For me, it’s the greatest stadium I’ve ever played in. I really believe that, with the atmosphere you get. The drive through Cardiff, as an away team can be a bit ropey. It’s f***ing brilliant.”
