  We geometrize six-dimensional pure $\mathcal{N}=1$ Supergravity by means of
an exact Courant algebroid, whose Severa class is defined through the
Supergravity three-form $H$, equipped with a generalized metric and a
compatible, torsion-free, generalized connection. The Supergravity equations of
motion follow from the vanishing of the Ricci curvature of the generalized
metric, satisfying a natural notion of self-duality. This way, we interpret the
solutions of six-dimensional pure, $\mathcal{N}=1$, Supergravity as generalized
self-dual gravitational monopoles. For the D1-D5 black string solution, we
explore the possibility of controlling space-time singularities by using
$B$-field transformations.
