Louville is a lunar crater on the western edge of the Sinus Roris, a bay in the northern part of the Oceanus Procellarum. It lies to the northwest of the crater Mairan, on a triangular section of continental terrain to the west of Sinus Iridum and the Mare Imbrium. This crater formation has been heavily eroded by impacts, to the point where the surface is somewhat difficult to distinguish from the surrounding rugged terrain to the east. It is now an irregular depression in the surface, with worn, uneven features. (wikipedia entry)
