Birmingham is the surviving remnant of a lunar crater.It is located near the northern limb of the Moon, and so is viewedfrom the Earth at a low angle. All that survives of the originalformation is an irregular perimeter of low, indented ridges surroundingthe lava-resurfaced interior. The inner floor is marked by severaltiny craterlets, and the surface is unusually rough for a walled plain.The low angle of illumination allows fine details of this boulder-strewnfield to be seen more clearly.

The Birmingham formation lies just to the north of the Mare Frigoris, and to the east of the walled plain W. Bond. To the northeast is the smaller crater Epigenes, with Fontenelle to the northwest.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Birmingham.
