Results are presented which show a new region of polarized emission aligned with the Continuum Arc of filamentary radio structures perpendicular to the plane of the Galaxy and about 30 pc away from the Galactic center. The structure of this region has the form of a central component with two jetlike outer lobes. The associated total intensity maps at 4.75 and 10.7 GHz show that the core and lobes lie symmetrically with respect to arched filamentary structures lying both above and below the Galactic plane. Only the arches above the plane had been seen previously. The remarkable symmetry of the region suggests the location of a new 'center of activity' within the Galactic center region at the position of the polarized core; however, total intensity maps do not distinguish this region at all except at low frequencies.
