In this paper, we construct dark halo models which are merely supported by geometry of space time. We concentrate on the inhomogeneous space time around some spiral galaxies whose have dark matter. After characterizing the dark halo models, the possibility of the energy density of such a field which could justify the rotation curves of stars in the dark halo is explored.
