The Carp played their last regular season game at Hiroshima Municipal Stadium (Hiroshima Shimin Kyujo) on Sunday against the Swallows (they could possibly play there again if they win the Central League Climax Series and play in the Nippon Series). They will move into a new ballpark next spring. There's a discussion of the new park and pictures here.
Here's the old ballpark's card from the 1992 BBM ballpark subset (#107):
This is the fourth ballpark in the 11 card subset that is no longer in use, joining Heiwadai, Fujiidera and Nagoya.
Update: I'd meant to include a link to Deanna Rubin's post about her visit to the ballpark also. Great pictures as always. Also, in this week's Pro Yakyu Weekly, Michael Westbay points out a couple of related links - one to Wayne Graczyk's Baseball Bullet-In column in the Japan Times dealing with the closing of the ballpark and to the Japanese Wikipedia entry on the park. The Japanese Wikipedia entry on the new park has photos of the model and of the construction.
Finally, here's the Google Maps view of the old park:
