The Galactic Center non-thermal filaments (NTFs) are a unique class of objects found only in the inner 150 pc of the Galaxy. These NTFs are oriented essentially perpendicular to the Galactic plane and extend for 10's of pc in length. Polarimetric data indicate that the emission is synchrotron in nature, and estimations of the magnetic field strength are in the range of a few mG, several orders of magnitude greater than the field strength in the outer Galaxy. The NTFs therefore are good tracers of the vertical magnetic field configuration in the center of the Galaxy. Multifrequency, polarimetric observations made with the VLA of the Northern and Southern Threads and the Snake NTFs are presented here. Spectral index, rotation measure, and intrinstic magnetic field information will be discussed in each case. In addition, recent high resolution observations of several newly classified Galactic Center NTFs will be presented.
