Gloucester have confirmed that Wales and British and Irish Lions hooker Richard Hibbard will join the club from the Ospreys next season.
Hibbard will team up with World Cup-winning All Blacks prop John Afoa at Kingsholm next season.
Hibbard made his Welsh debut against Argentina in 2006 and scored his first international try against Scotland at Murrayfield in the RBS Six Nations in 2013.
He featured in all three Tests for the Lions in Australia this summer, starting the decisive 41-16 victory in Sydney.
The 30-year-old has made 171 appearances for the Ospreys, having previously played for Taibach, Aberavon and Swansea.
Gloucester director of rugby Nigel Davies said: "As with the recent confirmation of John Afoa's signing, Richard agreeing to join Gloucester next season is fantastic news.
"Balancing the squad, and adding depth in key areas has been a key objective for us, and this news is another part of that process.
"It shows where we're heading as a club. We're building a team armed not just with power up front, but also the ability behind the scrum to play a rounded and complete game.
"It is testimony to the hard work and commitment of everyone at the club. We're able to invest significantly in our team thanks to the backing of our board, the continued financial success of Gloucester and the significant investment made by our partners, sponsors and supporters."
