  We present preliminary results from mapping the high-latitude Galactic
polarization with the Effelsberg Telescope at $\lambda$21 cm. Structures on the
resulting maps are mostly on the scale of several degrees. The results show
detection of polarization over most of the field, at the level of tens of
percent of the synchrotron emission. The evidence of more structure in Stokes Q
and U rather than in $\sqrt{Q^2+U^2}$ suggests the existence of Faraday
rotation.
