Birmingham is the surviving remnant of a lunar crater. It is located near the northern limb of the Moon, and so is viewed from the Earth at a low angle. All that survives of the original formation is an irregular perimeter of low, indented ridges surrounding the lava-resurfaced interior. The inner floor is marked by several tiny craterlets, and the surface is unusually rough for a walled plain. The low angle of illumination allows fine details of this boulder-strewn field to be seen more clearly.
The Birmingham formation lies just to the north of the Mare Frigoris, and to the east of the W. Bond walled-plain. To the northeast is the smaller Epigenes crater, and Fontenelle crater lies 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 crater.
