Wales have confirmed their pre-World Cup Test schedule next August which is highlighted by home and away games against England.
Warren Gatland's men will travel to Twickenham on August 6 followed by a Millennium Stadium return seven days later, before hosting Argentina on August 20.
Wales' opening World Cup pool game is against South Africa in Wellington, New Zealand on September 11.
A home game against the Barbarians, meanwhile, has been announced for June 4 to mark the Welsh Rugby Union's 130th anniversary.
"I am delighted at the schedule of warm-up fixtures we will be playing in June and August next year," said Wales coach Warren Gatland.
"We will have a prolonged camp for the squad to prepare, and it is important for us to measure our progress against some top-class opposition."
