The French side are changing all their seats at their current stadium to red.
Celtic Park is one of a kind. The 60,355 capacity stadium in Glasgow is one of the most exciting venues in European football and The Bhoys are very proud of their home ground.
But, oddly, there could soon be another Celtic Park in Europe.
Rennes currently play at the Stade Route de Lorient. But this summer the stadium, which currently has multicoloured seats including green and blue, is being revamped.
The seats are being changed to entirely red this season to reflect the club's colours.
As part of the change the club are also asking fans to vote for a new name for the stadium. The names on the agenda are, as reported by 20 Minutes, Roazhon Park, Roazhon Hermines and ... Celtic Park Stadium.
The name has been suggested to highlight the Celtic cross' prominence in Brittany's heritage.
Celtic will of course be hoping the other names get the nod, as they do not want another Celtic Park stepping on their territory.
