Legion Field in Birmingham, once the largest stadium in the state, served as both a home field and a neutral field for the Crimson Tide.
It hosted the Iron Bowl between Auburn and Alabama for more than forty years, alternating as a home field for each team. The outcomes were not neutral, with the Tide 32-15 against Auburn in Birmingham.
The Tide also played home games against other opponents in Birmingham until a few years ago, usually two or three other games every season. They played the entire 1987 season at Legion when Bryant-Denny was being renovated. Auburn played home games against SEC opponents in Legion from time to time as well.
In an interesting quirk, though there have been several incarnations of bowl games in Birmingham, the Tide have yet to play in any of them.
