Wales forward Luke Charteris will join Bath from Racing 92 at the end of the season.
The 6ft 9in second-row has 62 international caps and played in all five of Wales' matches at this year's World Cup.
"It is such an ambitious club, and that's a great atmosphere to be joining," Charteris said.
"There is some incredible talent in the squad and I'm really looking forward to heading over and getting started."
Charteris was also offered a deal by Cardiff Blues but the 32-year-old opted for a return to Bath, where his family have a house and he studied at university.
Bath head coach Mike Ford added: "He's a superb athlete at the set-piece and in the loose, has strong leadership qualities and a lot of experience that he can bring to the squad."

Can't believe that Jonah Lomu has passed away. Was with him and his wife and family for an evening last month. So sad, life is so cruel.
RIP Jonah you were a true legend and a gentleman.You changed the game of rugby and will be sorely missed. My thoughts are with your family.
Woke up to sad news that the legend Jonah Lomu passed away. One of the Greats. RIP?
The head of the Welsh Rugby Union says doping bans for two club-level Welsh players serve “ as a strong warning to everyone in the game that non-compliance with anti-doping rules carries grave consequences.”
Merthyr RFC player Owen Morgan and Greg Roberts of Glynneath RFC both tested positive for traces of different prohibited substances during separate SWALEC Division 1 West games last season and have been banned from all sport for two and four years respectively.
The WRU launched a new country-wide initiative last year to highlight the dangers for players at all levels that intentional and unintentional doping violations bring whilst also providing information for players and coaches as to the rules surrounding the issue.
Those warnings though went seemingly unheard by the two latest players to be found in breach of the regulations, something Phillips hopes will serve as a stark reminder as to the dangers doping presents to anyone involved in the game.
“There is no place for doping within sport, and it certainly doesn’t fit in with the values of rugby union. Whether intentional, or inadvertent, players have a responsibility to themselves, to each other, to their clubs and to the sport to act within the rules and spirit of the game.
“We work closely with UK Anti-Doping and fully adhere to the World Anti-Doping Code. There is no room in the code for carelessness or not knowing, and players are encouraged to check the prohibited lists, found via the WRU website which include over-the-shelf medication and supplements.
“We want to rid our game of these practices and we encourage anyone who has any intelligence of doping taking place to call the WRU or UKAD and help protect our game.”
The WRU has warned players at all levels to be vigilant about what they consume after two club level players were banned from all sport by UK doping authorities.
Merthyr RFC player Owen Morgan and Greg Roberts of Glynneath RFC both tested positive for traces of different prohibited substances during seperate SWALEC Division 1 West games last season.
The pair have been banned from all sport for four and two years after failing in-competition tests.
That has prompted the Welsh Rugby Union to urge players right across the leagues to be wary of anything they take that could contravene anti-doping rules.
“The Welsh Rugby Union has issued a strong warning to players at all levels of the game to ensure they train and compete cleanly for the good of the game following suspensions of two players for anti-doping rule violations.”

Wales coach Warren Gatland has indicated he'll leave Wales in 2019 in an interview with a New Zealand radio station.
Talking to Matt Brown on Radio Sport Gatland was asked: "Are you determined to have another crack at the Lions job?" and he replied: "Yes, if I get offered the opportunity."
The presenter then asks: Do you still have ambitions to coach again in New Zealand? Gatland replied:
Absolutely.... I'm here (in Wales) until 2019 and the plan for me then is to come home for a period...
If I was involved in rugby that would be great but if I'm not I might have to go to the beach for six months or twelve months and take a bit of a break.
Wales' longest-serving coach took the helm in 2007, and has claimed two Six Nations Grand Slams in his tenure.
The WRU declined to comment.
