I review the observational properties of interstellar magnetic fields in our Galaxy, starting from the large Galactic scales and gradually zooming in toward the heliosphere. It emerges that the large-scale magnetic field is predominantly azimuthal in the Galactic disk, but that this global field orientation is severely perturbed in the small-scale surroundings of the heliosphere. 2 1 The argument usually put forward to justify the equipartition assumption is that energy equipartition
