Sam Warburton and Danny Care have ranked the tournament's stadiums.
#6. Stadio Olimpico (Italy)
Care: "I think as a fan, as a weekend, I'd say it's one of the best. As soon as you know you're away to Italy the families start booking their flights."
Warburton: "It's a really long walk out and it's like you're going into some sort of gladiatorial battle the way you had to climb up the stairs and the stadium would open up in front of you."
#5. Aviva Stadium (Ireland)
Warburton: "I loved it at the Aviva. The pitch was immaculate. Changing rooms immaculate. Stadium is stunning."
Care: "We've often played there on St Patrick's Day and it's an incredible atmosphere. You get that fun, festival-type vibe but you also get the vibe that you're not very well liked as an Englishman."
#4. Stade de France (France)
Warburton: "It's a beautiful stadium with lovely big changing rooms, really grand, very French as you can imagine."
Care: "When France are on it, I don't think I've heard noise like it. But when they're off, it's worse than Twickenham - they will boo their own team and whistle."
#3. Murrayfield (Scotland)
Care: "When you get off that bus at Murrayfield and they are so close to the bus calling you all the names under the sun... we've had bottles thrown at us, we've been doused in beer."
Warburton: "I love the stadium and even though it's old, it's unchanged from when I used to watch rugby as a kid. I love the friendly Celtic rivalry, the history, the bagpipes... the stadium is old but it's unique."
#2. Twickenham (England)
Care: "Twickenham is the home of rugby. I remember the first time I ran out I was like 'wow, this is cool' and I had tears in my eyes."
Warburton: "I loved the way the bus would come in. You go through a few high streets and you can see people in the pubs in England shirts and the bus pulls up about 100 metres away from the stadium."

#1. Principality (Wales)
Warburton: "[It's] the proximity to the pitch and how close the fans are to the action. We had to have body language [line-out] calls because we couldn't physically hear each other."
Care: "This is why I love the Principality: genuinely you will see 90-year-old women sticking two fingers up against the bus as you drive through the city centre."
